Honestly, this book was boring, and the worst thing a mystery/thriller book can be is boring... 
This was my first Freida McFadden and it will definitely be my last, I didn't get along with the amateur writing, it was so simple and over explained everything the characters did. Like at one point there was a whole paragraph of Natalie one of the main characters talking about how cold it was and how if it really was freezing the water would've been ice, like just not necessary. 

It wasn't even exciting and the twists did almost nothing for me, like I'm someone who is almost always surprised about twists but I was just like 'Oh, well there ya go' about this one? 

I also REALLY disliked the way the character Dawn was portrayed, she felt VERY autistic coded without saying she was and all the other characters made fun of her, or realised she was crazy BECAUSE of these traits and it just felt like Freida was making fun of autistic people tbh. It was uncomfortable to read. 

The characters had almost no substance, I wasn't rooting for any of them quite honestly, and when all of the characters are unreliable narrators it makes the book super boring cos you know every perspective you hear is just someone messing with you to try and shock you in the end. 

I finished it, which is why i've given it 2 stars, but this has cemented that I don't want to read anything from her again. Sorry Booktok
