I just finished The Sister Switch by Charlotte Butterfield, and I am obsessed in the best possible way! You know that rare kind of book that makes you laugh out loud, swoon uncontrollably, and maybe rethink all your life choices because you’re that invested? Yeah, this is that book.

From page one, I was completely hooked on this delightful, chaotic, and ridiculously fun twin-swap adventure. The premise? Brilliant. The execution? Flawless. And the romance? A chef’s kiss combination of flirty banter, mistaken identities, and the kind of heart-melting moments that will have you grinning like an absolute fool.

Charlotte Butterfield knows how to write characters that feel like friends, humor that actually lands (I cackled multiple times), and romantic tension so perfectly built that I practically held my breath waiting for everything to unravel in the best possible way. The relationships—both romantic and sisterly—are warm, messy, and full of heart, making this story so much more than just a fun rom-com.

If you love laugh-out-loud moments, swoony romance, and a storyline that keeps you flipping pages at an unhealthy speed, then trust me—you need The Sister Switch in your life ASAP. Highly recommend, 10/10, no notes. 💖✨

⭐️⭐️⭐️⭐️⭐️ (5/5—READ IT IMMEDIATELY!)

I am the oldest, with a brother and two stepbrothers!
Growing up as the only girl, l often wondered what it would be like to have a sister and a twin... maybe that's why The Sister Switch was such a fun read! It was fast-paced, filled with sibling drama, personal growth, and self-discovery. While I couldn't relate to the sister dynamic, I loved stepping into Alice and Edie's world and watching them navigate it LITTERALLY in each other's shoes.

this might be the funniest book i’ve read in 2025!

these two sides of the same coin twins are nothing alike, don’t get along, and switch places to get a taste of one another’s lives. the characters are so well crafted and it was easy to connect with them.

this is such a warm, easy read that I can see it appealing to a commercial audience. if you’re looking for something easy to read, warm and deeply funny, this is for you.

Thank you Netgalley for the advanced copy! My opinions are all my own.

So, as I'm an identical twin myself, I couldn't NOT request this book when I saw it first existed.

There are many things that people say to twins on a regular basis:
- I'm seeing double!!
- So do you feel it if the other one is in pain?
- It's always been a fantasy of mine... (too gross to type.)
- How do you know who is who? (Well I'm me and she's not... so...?)
- You guys should look exactly the same/You guys should look different! (replace with any aspect of ourselves, 'should' is heard a lot.)
- Any form of "weird" (You're twins?? That's so weird!. You went to the same university? That's so weird! etc.)
- Stand next to each other! (Proceeds to point out our differences/insecurities as if we're not right in front of them... e.g. 'You're chubbier than her', 'You've got that weird red mark there' etc.)
...
(God, I could go on forever)
...
- And the classic: Have you guys ever tried to prank people by swapping places? That would be SO FUNNY.

You know what, we did once. It was incredibly boring.

Spoiler: people confuse the two of you for your entire lives, including your own parents. So when the outcome of taking the time and effort to swap clothes, copy each other's slight difference in voice, and stand taller/shorter respectfully, is simply being called by the other's name instead of your own... it just feels like a regular Wednesday to me.

BUT this review isn't about my life, it's about this book!

I've been where Alice and Edie have been a couple of times, so distant and annoyed at my sister that I worried we wouldn't get through it - honestly the beginning of this book was hard to read it was so close to home. But even when they're at their worst, they still couldn't imagine not having the other in their life, which is so lovely and so like me and my sister.

I also really loved that the set up for the two swapping places was that it used to be what their mum made them do to 'see what it was like from the other perspective and have more empathy'. She seemed like a lovely mum.

All the dynamics between the characters were very well written, even with Danny (who I very much wanted to slap for most of the book) and the kids felt all like real people, even when they weren't really on the page for long and that's a great skill in writing. I found myself aww-ing and tutting out loud when reading, which is rare for me, I'm usually a silent reader, but this book just made me feel so engulfed in the worlds of Alice and Edie that I couldn't help but feel like everything happening was so real.

The only minor thing I suppose I didn't like would be how quickly some of the issues that I think are major get resolved. I mean, some of that must have been to show the difference between Alice's husband and Edie's partner, but even so that slightly bugged me.

But aside from that, this was a really well written true-to-life book about what it's like being a twin and managing to have space for both love and resentment for someone who you are so utterly close to. Give it a read if you've ever been curious about 'what it's like being a twin' (yes, another common question!) and if you just want a heart-warming cosy read.

This was such a good book. I loved the story and the writing so much. The characters were great and the story flowed smoothly. Will definitely read more books by this author in the future.

I expected to enjoy this as I have enjoyed other books by this author, and I did enjoy it very much…

Edie and Alice are identical twins, so identical that they can swap places.. This, they do, dress as each other for a short while. Except they both can’t help themselves from trying to fix the other twin’s life. They don’t tell anyone that they are switching, not even Seb, Edie’s partner, or Danny, Alice’s husband.

Edie is a very likeable character, and so is Alice when she wakes up to what’s going on in her life. Seb is the most adorable man ever, he’s perfect. Danny is the worst man ever, he’s as imperfect as they come.

This book is immensely fun, and it deals with some heavy issues as well, it isn’t frivolous.. You do slightly have to suspend disbelief that neither the children nor partner of each twin could tell that they had swapped. Only their dad was able to spot that they’d switched, and it was him that gave them the idea to do it. Danny probably wouldn’t notice Alice was different, but I’m sure Seb would, especially when “Edie” was acting out of character.. The author does use some creative ways to explain away how they could get away with it, so you can happily accept that nobody spotted their ruse.

I’d recommend this to anyone, it’s a really good book. One you can’t put down, which is exactly what you want.

As a girl who has 3 sisters who we all argue and bicker at times and do not understand each other or truly know each other on a deep level, I relate to this. Though Alice and Edie are twins, it made it even deeper. Some parts truly hit me while they were switched, and it made me think of my sisters and their lives differently. I'm not gonna lie, their dad Kenneth was remarkable and definitely one of my favorite characters in the story. Seb was also AMAZING, the best book husband!! I found it beautiful watching both sisters' character development throughout the story. I loved this, and it truly touched me at so many different moments!

I received this ARC from NetGalley and Avon Books to read/review. All of the statements above are my true opinions after fully reading this book.

This book made me laugh out loud. It's funny engaging and light hearted with some emotional parts.

A pair of identical twins who are nothing alike amd dont get on, switch places to learn what the others lives are like to see things from theor perspective.

The characters are created well with enough background so they build the story. I really disliked Danny, but I suppose we were supposed to. I liked the ending, It would have been better if it had a little more in the way of Danny getting what he deserved.

A warm funny easy read story that most people will enjoy. It's written well and kept me reading. I would recommend this book to read for a new perspective on life and how we don't always know what someone is going through.

I would like to thank Netgalley and the Publisher for the opportunity to read and give an honest review of this book.

I LOVED this! I was in a reading slump for a while and this has 100% pulled me out of it. I couldn’t put it down! I read it in one day - if you’re wanting a pick me up, this is it! It’s funny, well written and I loved the characters- amazing! Thank you for my ARC!

From start to finish, this novel does not lose momentum and I could not put it down. The characters are so well rounded and relatable and the plot is funny and realistic. I did think that Danny and his parents could have been given a tiny bit of empathy - they are vey unsympathetic. This author is very talented and I loved this book.

I absolutely adored this book! I loved this book on sisters as I always wished I had a sister. It was so fun watching them sap but also heartwarming and fun as well. It came with slit of life lessons and grass isn’t always greener on the other side mentality. High recommended

I loved this . Funny, sad and a great read. Identical grown up twins swop lives . Oh my. No one has the perfect life. I gulped at a a couple of things. You always think someone has a better life than you realise . Don’t meddle . Could not put it down. Neat ending .

Two sisters, very opposite decide to switch lives. This book is cute, funny and very relatable!
Easy to read and follow along.
I’d definitely recommend if you like light hearted comedy novels

The Sister Switch by Charlotte Butterfield is a delightful and thought-provoking book that blends humour, emotion, and family drama. It follows twin sisters Alice and Edie, who may look identical but are complete opposites in personality and outlook. Their fiery debates on their morning TV show keep audiences entertained, but behind the scenes, their relationship is far from harmonious.

After a particularly heated on-air clash threatens their careers, they make a bet—each is convinced that the other could never last a week in her shoes. Determined to prove each other wrong, they secretly swap lives without telling anyone. What starts as a light-hearted competition quickly turns into something much deeper as they navigate each other’s personal and professional struggles. From marital issues to awkward work dilemmas, both sisters discover that the other’s life is far more complicated than it seemed from the outside.

The book is full of funny, heartfelt moments as Alice and Edie meddle in each other’s lives, making changes they believe are for the best—without necessarily considering what is truly needed. But through the chaos, they learn valuable lessons about themselves, each other, and the importance of empathy. Their rivalry slowly shifts from a battle of wills to a chance for genuine growth and understanding.

Butterfield does a brilliant job of capturing sibling dynamics, making this a touching and entertaining read. The insights into each sister’s life are relatable, and readers will likely find themselves identifying with elements of both Alice and Edie. The book is perfect for fans of David Nicholls, Sophie Kinsella, and Cecelia Ahern, offering a fun yet meaningful exploration of family, identity, and self-discovery.

This was such a fun read!

Identical twin sisters who have grown up with polar opposite personalities - one laid back and live and let live, the other uptight and obsessively hoovering and dusting everything in sight. They both think their way of life is better than the others, so agree to have a life swap for a week or so, without telling their partners or children. They can't but interfere in the other sister's life, making changes that they deem better without stopping to think what might be best.

I loved the insights into each others' lives and the relationship between the two and I think I've taken a little something from each sister!

I devoured this in a day! A perfect light and funny read. The characterisation was great and the story was fun. If you like wife swap you’ll like this! Seems mad though that the only person who knew they were switching was their dad!

The Sister Switch by Charlotte Butterfield - Morning TV’s favourite twin sisters, Alice and Edie, may share the screen, but that’s where their similarities end. Their viewpoints are far from identical, and whilst their on-air clashes keep viewers hooked, off-camera, their relationship is far from picture-perfect.

After a heated argument on live television threatens their jobs, the fiery duo make a neither could last a week in the other’s shoes. Determined to prove each other wrong, they secretly swap lives — without telling a soul.

I went into it thinking that I wouldn't enjoy it and surely their spouses and children wouldn't fall for their switch, but they did, and it made me realize how complacent we can become in our lives and not pay attention to what's going on.

Both Alice and Edie were relatable in their own ways and it was easy to find both of them likable, but I was uncomfortable at first with the whole switching husband's aspect of it. Once I got over that, I enjoyed the whole book and wanted more at the end. A Parent Trap kind of book for adults, in a way.

Thank you to NetGalley and the publisher for this ARC in lieu of an honest review. All opinions are my own.

Having read and enjoyed Charlotte’s previous story The Second Chance, I had high hopes for this new book and what a treat it is. I’m often dubious of the words ‘hilarious and uplifting’ having read books before waiting for the said hilarious and uplifting parts only to end the book disappointed, but I really did find this story both hilarious and indeed, uplifting.

We meet identical twins Alice and Edie who have a weekly TV slot as ‘agony aunts’ on a morning show which viewers enjoy because of their constant bickering with opposite points of view. One morning after a particularly heated debate they find their jobs at risk and decide the only way to make a truce is to swap lives as a bet that the other couldn’t live in their shoes without being found out. Although identical in looks it becomes very apparent that they have almost exact opposite home lives and so starts a challenging and very funny journey.

I found many laugh out loud moments in this book, especially from quick witted Edie who is the seemingly laid back funny twin compared with Alice who is uptight and stressed. But as in real life, once you get past the surface that everyone else sees, you get the depth of the real person which shows the strengths and weaknesses that they harbour deep down. There are sad parts in the book as well as the funny parts which make this very relatable and appropriate to everyone. Very well written, I thoroughly enjoyed this story and found all characters interesting, including the children whose challenges were also captured well, especially the change they highlighted in their moods in Alice’s family when they were in the presence of their father Danny compared to when he was out. Really thought provoking in my opinion, even if a little sad! It may be a little far fetched to think they wouldn’t get found out straight away by their own partners (or at least Seb) but put that aside and just enjoy this real cracker of a book.

Highly recommended and big thanks to Jessie Whitehead at Avon and NetGalley for an early copy in return for an honest review.

Such a great book! I love books abt sisters (wish I had one) !t was lighthearted, funny, and super emotional and touching as well! I love s good swap and it really shows what we think when the grass is greener on the other side. Loved her first book & really enjoyed this one! Hope there is much more to come from her bc her writing is fantastic

Alice and Edie are identical twins, but far from identical in personality.

Alice, who has a huge instagram following, is basically a trad wife, though she's never quite described as such. Her life is devoted to running a perfect home and making the lives of her husband and children as easy as possible, ensuring none of them have to lift a finger for themselves. In the eyes of husband Danny, who has some frankly prehistoric ideas about gender roles (no son of his is ever setting foot in a kitchen), that's exactly how it should be.

Edie, on the other hand, is far more chaotic and laissez-faire. Her house is a tip and partner Seb and their two daughters can and do fend for themselves, while Edie works all the hours to keep them afloat financially. Her feminist principles are totally at odds with Alice's choice of lifestyle.

Both, of course, are horrified by each other's lives. But who's happier?

When their inability to see eye to eye starts causing more trouble than ever - including during the weekly breakfast TV slot where they're joint agony aunts - drastic measures are called for. They often pretended to be each other as children - why not see what life is like in the other's shoes for a while?

So begins the switch, known only to them.

It was hard to believe that the husbands didn't notice - well, maybe not in Danny's case - he's hardly ever there and barely notices Alice when he is. And kids tend to be pretty self-centred. But the attentive Seb surely wouldn't have been fooled. And identical as they are, there must be differences- hair, etc. It must take more than just switching clothes. But it's fine to suspend disbelief for a while!

This was loads of fun, with lots of awkward situations which highlight the difference between the sisters' lives. I loved the contrast between the two book clubs.

Edie doesn't know whether or not Danny's full name is Daniel, which seems an odd thing to not know about your brother-in-law - surely she was at the wedding? And I did take very mild exception to the portrayal of Fife as the possibly worst place on earth- my daughter's at uni there and loves it!

Five stars anyway for a super fun read.
