I gave this book 4 stars because I liked it. I really did like it. However, I did not love it. 
 I am going to continue to finish the trilogy because it is captivating enough that I'm curious, but I might do it at a slower pace and read some other books inbetween to be honest. 
 So basically this book is about a girl named Violet who can sense the bodies of those that have died untimely (aka murdered) and also, their killers. There is an imprint or "echo" as she calls it that is attached to the victims, as well as an identical imprint attached to the killers. She found the body of a dead girl when she was 8 by sensing the echoes and that's when it all began. 
 This book in particular starts out her junior year of high school. She hasn't found a human dead body since she was 8. Her main problem at the beginning of the book is her frustration with her bestfriend, Jay, who she has developed feelings for. But under certain events and circumstances, other problems become more important (or at least in my opinon, they should be...). There are multiple murders of teenage girls around her area and eventually, she becomes very close to the killer. 
 It's pretty suspensful for those reasons alone and it's a fun read. 
 Likes: the general plot. Kimberly Derting had a good imagination with this one! The overall idea is interesting and compelling. 
 Dislikes: Her choice in the development of her characters. Violet is bland. Although there are many believable aspects of her that I enjoy, it seems that a huge chunk of the book she's complaining about her feelings for Jay when THERE ARE MURDERS IN HER FREAKING NEIGHBORHOOD. Some of the reactions throughout the town that Derting picked weren't believable, either. A girl would disappear and everyone would freak out for one day and then the next it seemed everyone went back to normal. Okay...So I live in a fairly small town and there's no way in hell that anyone would go back to normal after merely 24 hours. The difficult part about these characters is that they all seemed to be in their own little worlds (and I don't like ignorant characters). 
 Overall, I gave the book a 4 because I did enjoy the read. It was pretty quick and it did have a few good hooks. I do recommend reading it because it's only a trilogy so it's not super extensive and it really does leave you hanging.
