Edie and Alice are identical twins with very different outlooks on life. Edie is very bohemian in her outlook and Alice is quite buttoned up and outwardly the perfect mother and housewife.
When they have a blazing row on live television and after the intervention of their father, they decide to secretly swap lives. Edie must put up with Alice's overbearing misogynist husband and Alice with the carefree household that Edie shares with her partner and their children.
As the swap progresses, they both realise that there are things in their lives that could be changed. But when big decisions have to be made, can they be in the right place at the right time?
A fun book but with a serious undertone.

The swap situation is definitely interesting but realistically would not fool anyone lol but that’s what makes it fun to read I guess! And with my whole chest: FUCK DANNY! Jesus Christ.

Review also posted on goodreads!

A funny and light-hearted read which I thoroughly enjoyed. A life switch between two twin sisters who are so different in characters but look the same. I thoroughly enjoyed this story and didn't want to finish it. My thanks to Netgalley and the publishers for giving me the opportunity to read this book in return for an honest review.

Twins Alice and Edie may share a face as well as a seat on the top morning show but that's where the similarities end. Each sister has her own unique voice and most importantly opinion!

But when these differing opinions cause an all out on air fight, the duo are forced to try and save their jobs by spending a week in each other's shoes.

What follows is a medley of mishaps and misunderstandings as the sisters discover that the other half lives isn't always better.

A funny, laugh out loud romp

This was a really sweet, funny and emotional story about two identical twin sisters who have so much love for each other that they swapped lives to learn to see each other’s perspective so they didn’t lose each other to their bickering.

The sisters relationship is very on par for siblings I also love that the main characters are in their 40’s and I absolutely loved that this book is based in the UK. I loved reading British writing, never realised how much I missed it until reading it lmao.

The characters were enjoyable to read about I did worry just a teeny tiny bit about Alice because she wanted to stay switched for longer after realising how nice Seb is, so I was so relieved when the author made it very clear she had no attraction to him because that would’ve crushed me (and Edie).

Really loved the different family moments and I really felt for little Emily and Rufus (and later Teddy). The kids really added a great element to their stories.

The only complaint I have was that Seb didn’t realise that they had swapped, I know it’s the way it had to be to extend the swap but I’m really gutted he didn’t realise that Alice wasn’t Edie. Other than that, great book, great writing, very feel good and entertaining.

Thank you Avon Books UK + NetGalley for an arc - all opinions are my own.

The Sister Switch by Charlotte Butterfield was just the book I needed to read. It tells us about twin sisters Alice and Edie and how they decided to secretly swap lives. They wanted the other to prove to the other twin that their life was not what they thought it was. The author did a great job of making me feel like I was right there with the twins during the whole book.
I don’t have a twin, but I have to say that this book made me think about what it would be like to have a twin sister. This book was so much fun to read, and I know that there are a lot of twins out there who are going to relate to this story.
Thank you NetGalley, Charlotte Butterfield and Avon Books UK for the copy of The Sister Switch. This is my personal review.

I really loved this book! The story of sisters at a crossroads swapping lives in what starts as a bet, but turns towards understanding each other was in turns hilarious, heartbreaking and heartwarming. The story was well paced and engagingly written - I finished it the same day I started it! Alice and Edie were great characters- both with distinct voices and flaws, but both easy to root for. The families of both were also fully realized characters that added to the depth of the story.

Loved this story all about twin sisters who make a bet to switch lives for a week, Found myself laughing out loud and smiling throughout this book… If you love cozy stories, some cute romance… this book is for you!

The Sister Switch was a fun and heartwarming read. The premise of twin sisters swapping lives is always entertaining, and this book delivered on that front. The story had its moments of humor and emotional depth, making it an enjoyable experience overall.

However, I felt that some parts of the story dragged a bit, and certain plot points were a bit predictable. While the characters were relatable, I wished for a bit more development in their arcs.

Overall, it’s a light and enjoyable read, perfect for fans of contemporary women’s fiction looking for something easygoing.

I enjoyed this humorous and emotional story with its chaotic laugh-out-loud moments and poignancy. I like the relatable characters, events and relationship dynamics that invest you in the women's lives.
I received a copy of this book from the publisher.

A funny, emotional and thought provoking story; the Sister Switch will have you turning the pages faster than you can imagine!

The Sister Switch by Charlotte Butterfield was such a unique and well written story!
This was truly a thought provoking and heartwarming read.
I was totally taken in and couldn’t wait to see how things would resolve.
A funny, emotional and thought-provoking story.

This is a hilarious, heartwarming, and thought-provoking story about a pair of twins, who, although look alike but couldn’t be more different than each other.

Alice and Edie agree to disagree on just about everything. Alice is a Stickler for rules while Edie is a carefree spirit. They were so different to each other that they were offered a slot in a TV show to showcase their contrasting views. When their relationship hits rock bottom, they make a daring bet: to swap lives and see who can last longer in the other’s world without getting caught. The catch was the winner quits the TV show. But what started as a bet slowly enlightens the sisters why their twin was the way they were.

I enjoyed reading this book and loved the twins. The children were adorable and Seb was such a green flag!

This book is a heartfelt celebration of sisterhood and family bonds—one you'll find yourself wanting to discuss with everyone you know.

I really enjoyed this story of sisterhood which made me laugh out loud several times. Warm, witty, funny and packed with love and great (mostly) likeable characters. The premise of switching intrigued me and I felt that the learning both sisters had about themselves and each other was just glorious. One to read for sure.

This book was just so hard to get into and the sister switching premise really caught my eye. But this book kinda just missed the mark. Not my fave...

When identical twin sisters find they can no longer understand one another and begin to argue more than they can get along, drastic measures must be taken. The Edie and Alice make a bet that the other could live last a week in their shoes. What ensues is a story that packed a bigger punch then I expected.

As I started reading, I felt like I didn't much care for either sister, however as they swapped places and began to have their eyes opened to the experiences the other lived daily, I found I really came to care about both sisters. Each sister went into the experiment believing one thing, and came out realizing how important relationships, and each other in particular were to each other.

this is such a warming and heartfelt read. i was wondering how you would ever get away with or work the actual swap but i needn't have. it was handled perfectly and it never came up to my mind again.
it felt like we were somehow really getting to know the characters ourselves. so things we might once assume of both sisters if we had read a story of JUST them was suddenly knocked away because we now saw things from their side, or the others side and vice versa. and this is what the girls also managed. they havent the greatest of relationship. they are a clickbait pair on air yes, but off it there is so much angst between them. but then once swapped they suddenly see what the other is going through. and in doing so we do too. and it truly is the case of you never truly know what people are going through unless you are in their shoes. in this case we all get to step into the other sisters shoes. and so did they.
the other characters in the book were just as fabulous if not more so. they added golden sunshine to the book. the dad and Sebastian were characters written and portrayed to perfection.
this book just a wonderful read. and so much better than i could have imagined.

Thank you Avon books for inviting me to review The Sister Switch
The funniest book I’ve read in 2025 so far—The Sister Switch is pure feel-good chaos in the best possible way. From laugh-out-loud moments to swoony mistaken-identity romance, this twin-swap adventure is as charming as it is ridiculous (in all the right ways). Sure, you’ll need to suspend a bit of disbelief, but once you do, you're in for a wild, warmhearted ride full of flirty banter, sisterly mayhem, and scenes that will have you grinning like a fool. Charlotte Butterfield nails the balance between lighthearted fun and genuine emotion, crafting characters you’ll want to hug (or shake, depending on the chapter). It’s the perfect read to toss in your pool tote or carry-on, especially if you’ve got a fruity drink in hand and want something delightfully escapist. If you’re in the mood for something easy, funny, and full of heart—this is the one.

This is a warm, funny, and sharply observed novel about two very different sisters—uptight, organized Alice and chaotic, free-spirited Edie—who swap lives. The result is both entertaining and heartfelt, as each woman is forced to re-evaluate her choices, roles, and relationships.

The strength of the book lies in its well-developed characters. Alice and Edie are believable, flawed, and relatable, with a bond that shines through their differences. The story handles family dysfunction with realism and humor, offering a refreshing take on sisterhood and motherhood. While the central premise of the switch stretches believability—especially with partners and children involved—the emotional journey makes it worthwhile.

Fast-paced and filled with both wit and heart, this is a smart, engaging read perfect for fans of character-driven fiction.

Thank you to NetGalley for this ARC!

This book follows twin sisters who don’t see eye to eye and decide to swap places to get a better understanding of the other’s perspective. This book had so many fun moments and also really put into perspective what love looks like. It was a wonderful and fun read.
