Review: 
 Protagonist: So first off the protagonist is "you" as most of this book is told in the second person. However to make my review easier to write I'm going to refer to the main character as "Sunny" as that is the name she chooses for herself at the beginning of the book. So Sunny wakes up right in the middle of the subway train tracks, in the tunnel enough that no one sees her and right at the start of the book there is a train headed right for her. Talk about a way to kick off not only a book, but a series as well. Sunny has no idea who she is or what she's doing in Los Angeles. In her effort to find the truth she, survives a near train accident, gets framed for a robbery, and nearly dies a handful of times. Sunny was a great character to read about and while the second person point of view was a bit weird for me to adjust to being a male, I easily adjusted and it made for a more intense experience than if I had just read it in first or third person. 
 Romance: So there is a bit of a romance in here, and I'm not sure if it's the size of the book or the scarcity of the romance but it escalated rather quickly, however it went with the fast paced and intense feel of the book so I was all on board. The main love interest Ben is a great character, but we really don't know that much about him, in fact all we really know is what he tells Sunny, which still isn't a lot. There is a bit of a love triangle in this book, but it is the weirdest and most unique love triangle I've ever read. This is because the second love interest doesn't even appear in the present day setting of the book. I'm not going to say too much more about him because I feel like if I even say anything more about him I'm going to spoil something, but I am very curious as to how this love triangle turns out. 
 World-Building: So while this is more of a contemporary/realistic book, I did get a weird dystopian feeling to it. It isn't a dystopian by any means, but there are classic dystopian tropes that play into this book and weave through it in a very dynamic way. One of them being that I can't really see our protagonist getting through this duology alive without causeing major damage and taking down something huge. I kind of don't want to talk about the book too much because it's a mystery and if I give something away I will deprive you of an amazing experience. I will say that the world is richly built and wonderfully researched. For such a small book it packs a powerful punch. 
 Predictability: With this being a mystery book, or actually with it being an amazingly written mystery book I was always surprised at the twists and turns. I was kept in suspense pretty much throughout the book, which I'm not sure but I think is a new experience for me. I had no idea, still have only a vague idea of what's going on and I have to say that I'm a bit shocked that this is a duology seeing as I can see this story going on for at least two more books. 
 Ending: The ending was the most surprising of all. One because when I got to the final chapter I was so shocked and a bit angry that the story was almost over, and also because there is a crazy "holy crap what did I just read" cliffhanger attached to it. There are still so many things I want to know, and I can barely contain my anticipation of the second book, which I probably won't get my hands on for another year. 
 Rating: 
 This was a very easy five stars for me. It's action packed, fast paced, and full of so much mystery and suspense. I love this book so much and highly recommend picking this up. While it is a "thriller" it is in no way a horror story and probably won't scare you unless you scare super easy.
