Thank you to Netgalley and the publisher for giving me an advanced copy of this book in exchange for an honest review.

I have not yet finished this book but impressions so far are that this is a gripping read, one that many gamers would greatly enjoy as there's plenty of reference to gaming and gaming concepts within the book.
The main character, Mimi on first appearance was pretty unlikeable but as the story is progressing and you're getting to see more of her interactions with her granddaughter Addie, I'm beginning to warm to her. There's a fear deal of whit and sarcasm so far which makes for an amusing read. I'll return for a full review when completed.

This Is Not A Game is not a good book either. The first thing that hits you is that the writer can't make up her mind to write in UK English or US English. Drove me bonkers, first of all autumn then fall, then back to autumn and back to fall again as an example. Erratic spellings. The characters are very flat and don't seem to connect to each other. This is so far removed from Agatha Christie as it's possible to be. It's always worrying when this comparison is drawn. The plot had too many holes you could drive a double decker bus through. Poorly written, not much content. Could easily have been a short story. Couldn't even make up it's mind as to whether it was set in 2025 or the 1950s. Frankly, boring

Murder, martinis, and Mimi - what more do you need?

*This Is Not a Game* is such a fun book, think Cluedo & cocktails! Mimi is our fabulous 77 year old who attends a cocktail party with her granddaughter Addie and the bodies start piling up. Mimi and Addie have to trade cocktails for clues and figure out who’s bumping people off before they’re next.

The best thing about this book has to be Mimi & Addie together. Mimi is sharp, she’s funny, and she’s got that grandma energy that’s totally iconic. Addie’s more grounded and emotional, and their dynamic together is super sweet.

If you’re into cozy mysteries with grandmas, high-society drama, and the occasional cocktail inspiration, *This Is Not a Game* is 100% worth a read.

Thank you NetGalley for the ARC and I hope there is more to come from Kelly Mullen!

Thank you for the opportunity to review this ARC of "This Is Not a Game". Set on a remote island in the middle of a snowstorm, in a locked mansion, murder occurs. It is down to Grandmother and Granddaughter duo Mimi and Addie to solve the murder.

I really liked this book overall, it gave me vibes of Agatha Christie's "And then there were none" but wasn't a copycat of it. I was intrigued throughout who the murderer was and it kept me guessing with subtle clues along the way as to who it was, so it wasn't a huge surprise at the end. I liked the gamer references and it felt almost believable in a silly kind of way.

I did find some of the character relationships a little farfetched and didn't like how distant the relationship between Mimi and Addie was as it became a bit unbelievable that they would work together if they didn't get on very well.

Overall a cosy-ish mystery, with lots of intrigue, well developed characters and a good plot

A very enjoyable book. Mimi receives an invitation to a party but it also includes a blackmail letter. Nervous about going on her own she invites her granddaughter, Addie to join her. Set on the island of Mackinac (pronounced Mackinaw) a fierce storm blows in. When the host is murdered, Addie, who is a developer of a successful murder mystery computer game, starts to investigate. Although it is a 'And then there were none' type plot, the characters are eccentric and written with a humour. Everyone has something to hide so with each interview more lies are revealed. It's an easy read and I read it over a 24 hour period. I look forward to more by this author.

Unfortunately this wasn't for me, I found the writing style hard to get into and the story lacking. The characters fell flat and the story was similar.

It's early November on Michigan's Mackinac Island, and 77 year old Mimi has been blackmailed into attending the scandalous Jane Ireland's auction at her isolated mansion, which she's co-hosting with her son-in-law (who's also her lover). In a bind, Mimi ropes in her heartbroken granddaughter Addie to attend the auction with her. But also in attendance are numerous other frenemies of Jane's, including the unlikely named Jim Towels. But as the storm takes hold, and the auction starts, so too do the murders. Soon Mimi and Addie find themselves the prime suspects, so both being puzzle fans they decide to turn detective to find the guilty. In doing so they discover that Mimi isn't the only blackmail victim, not by a long shot.

Although a murder mystery, this book was so funny, with some definite laugh out loud moments. The mansion shut off from the rest of the island by a moat, with the storm and the rising body count, and a cast of characters, almost all of them with something to hide, gives off And Then There Were None vibes. Add to that it's many secret passages which helps to increase the tension. You then have Jane Ireland, the 70-something narcissistic socialite, who's understandably estranged from her only child for having an affair with her son-in-law, both of whom have their own secrets. And then there's the relationship between Mimi and Addie, recently strained due to a falling out, who have to work together to bridge the generational gap and investigate the murders, and in doing so they start to see and appreciate the other's point of view.

This was really good, and I recommend it when it's published on 24th April.

I found this book really hard to read as the writing style felt like it was going to be set in like the 40s to 60s but then with the mention of fitbits you know this is set in present. So for me it felt odd reading.

Irascible grandma brings her game designer daughter to a dinner party and murder ensues. There's a moat with a raised drawbridge and a snowstorm, so the guests have little to do but mingle, bitch, and worry about who's next.
The various guests and staff are well-drawn, even the house itself has secrets, and it all adds up to a lot of fun - even with the necessary video gamesplaining for anyone who isn't a gamer (I am, and I would play the heck out of Murderscape).

I usually enjoy a locked room murder mystery having cut my teeth decades ago on Agatha Christie and thought with the side interest of modern day virtual reality murder games this would be a great book. Unfortunately I found it very slow going with two dimensional characters and the dialogue was so unrealistic which made reading it like wading through treacle. I did consider not finishing it, but pressed on to the end, which was supposed to be like a Hercule Poirot denouement but was more of a damp squib.

A fun murder mystery but slow throughout, I kept reading but only because I had hoped it would pick up pace

This is a fun locked-room murder mystery set in the US. Although I didn’t especially like the granddaughter-grandmother duo of detectives, the plot, characterisation and dialogue kept me well entertained, and I am looking forward to reading more by this author.

A slow starting locked room type mystery involving a dinner party in an isolated big house.

Lots of characters but none of them were particularly interesting and the detectives (for want of a better description) were no better. The fact that they were grandmother and granddaughter was also odd. I lost the enthusiasm for the book as the plot involved video games and the gaming industry./IT knowledge.

The slow start didn't really speed up, and I felt really disappointed in the whole book.

Thanks to Net Galley and Random House UK Cornerstone for the chance to read and review.

I didn't love this as much as I wanted to, but I did like the relationship between Mimi and Addie. I found it very far-fetched with some rather large plot holes. I read it in one sitting, but I did doze off several times which isn't a great advert for the speed of the plot.

I'm glad I read it, but I wouldn't rush back to it.

Thank you to netgalley and the publishers for my copy of this book.

Agatha Christie in modern form! This felt like everything I LOVE about a classic murder mystery, it grabbed my attention and held it the whole time, I couldn't put this book down, and if I did I was constantly thinking about what could possibly happen next... and ultimately - whodunnit!
Fantastic story I look forward to more from Kelly Mullen

I really thought from the cover and the description that this would be right up my street. Unfortunately it just wasn’t for me.

I felt like the book just dragged on - it could have been halved and still fitted everything in. I found myself struggling to reach for it as I wasn’t engaged.

The characters weren’t very interesting, not even the two FMCs. There was such potential for them to develop - both personally and in their relationship but it just didn’t happen!

This murder mystery has the flavour of a golden age Agatha Christie tale, with septuagenarian Mimi and her heartbroken granddaughter Addie finding that circumstances press them into service as detectives when a social event on Mackinac Island goes terribly wrong.

First, their hostess, Jane Ireland, cops it. And shortly thereafter, the second murder is discovered, leading to the need for urgent action! Witty and atmospheric, this story delivers beautifully, earning itself 3.5 stars.

If you love murder mystery then this is the book for you.

Brilliant story line just a bit long winded for me.

Really enjoyed this book, interesting setting, very atmospheric, I actually felt like I was there!

Mimi recives an invitation from Jane a local socialite who lives in a very grand mansion to attend a charity auction, unfortunately Mimi is left with no choice but to attend the invite also comes with a blackmail letter. She invites her granddaughter Addie to attend with her.

Mimi and Addie have been estranged for a while due to Addie's ex-partner who has since left her and seemingly stolen and sold from underneath her a computer game that Addie invented..

A snow storm brings the charity auction to a halt and everyone who is attending the event gets stranded in the mansion.

Great characters, great writing, interesting story, thought it really flowed well.

One small thing, Jane was spelt Jayne for the first few chapters.

Highly recommended

I thoroughly enjoyed this book. Mimi lives on an island called Mackinac quite happily. She keeps herself to herself and turns down invitations from neighbours. One day she receives a invitation from a local socialite to come to a charity auction which she plans to turn down. Then comes the hook. Mimi receives a blackmail letter and she knows she has to attend to find out what Jane knows. As much as Mimi is not a person to scare easily she invites her granddaughter, Addie, to come to the auction. Their relationship has not been good over the recent past – Mimi did not approve of Addie’s partner, Brian, but as they have gone their separate ways, Mimi feels the time is right to mend this. Mimi and Addie attend the auction and things go from bad to worse. A snow storm arrives and the visitors are all stuck at the huge house. Murders begin, first Jane. The Police cannot get to the island so Addie as a writer of video games brings her logic to the fore to find out the truth behind the murders. I changed my mind throughout the book who the murderer was – sign of a good story well written. I thought this was a good book and it flowed from start to finish. I love the interaction between Mimi and Addie.
