I got this book as BOTM pick because the synopsis and cover reminded me of a phone game I liked to play, I know weird reason to get a book. So I thought it was just going to be a fun little thriller mystery, but it really grabbed me. From the very first chapter, I was itching to know what had happened 5 years ago, what the secrets were, who's lying, what happened to Kaavi, and then even in the final chapter there's one last little twist. All the characters, starting with the main one Amaya, are unreliable narrators. They all have secrets, they all lie, they all want to protect themselves and until the end you don't know who to trust. 

I really liked the mystery, I thought the author did a really good job jumping between past and present creating a timeline of events, and I appreciate that there are no loose ends, every mystery and secret is revealed because, personally, I find it annoying when I'm reading a mystery and end up with more questions than answers but what took this book from 4 1/2 stars to 5 for me were the final chapters which focus on Kaavi's POV. Not only because we get to finally see who she really is and we get a lot of answers but because we get to see that she and Amaya aren't that different after all.
