I received a copy of this book as part of the Goodread First Reads giveaway. All opinions are my own. 
 I really hate to do this but I gave this book a 2.5 stars. 
 There were so many things about this book that I just did not like. This book reminds me a lot of Kimberly Dertings The Body Finder series. Instead of her being able to sense dead things, she sees things like numbers and letters in color, among other things. The synethesia was all just so confusing. After a while I couldn't stand it. 
 Let me go into the reasons why I had to put this book down before finishing it: 
 1) Nikki is the worse female heroine ever; she smokes, has sex, never goes to school despite the fact that she's on academic probation and in jeopardy of not graduating, hates everyone in the book especially other females in the book, and is not the brightest cookie in the jar. NO ROLE MODEL OF THE YEAR AWARD FOR NIKKI KILL. 
 2) Engages in a sexual relationship with Peyton's older brother(the victim) who is suspected of attacking his sister and has sex with him after Det. Martinez tells you he's a suspect and you do it in the victims home. 
 3) She pursues her own investigation because she believes the police don't know how to do their jobs, when she is the one hindering their investigation by stealing evidence and not reporting things she finds and tampers with evidence and impedes an ongoing investigation. 
 4) Her only parent is her Dad who does nothing about Nikki skipping school or has no idea about her nightly activities of playing the P.I. 
 5) She practices karate and literally thinks she can kick every person she meets ass. Give me a break. 
 6) She continuously puts herself in danger and does not think through a single thing that she does. She makes terrible decisions like tries to wear a disguise that does nothing to conceal her true identity, breaks into people's homes, goes to scary places at night and alone, etc. 
 I'm not trying to bash the author or the book, but I did not like this book at all. It really makes me sad because I hate to not finish a book. I do want to read other books by this author.
