The main character of Charley Davidson is definitely very likeable and down-to-earth, but I thought at times she came off as too "smartass" and a little rude. I think there was a change in one of her colleagues, Garrett, by the end of the book, and I really want to see more of him. I'm actually more drawn to the Garrett character, to be honest, than to Reyes. 
 One thing I didn't like about this book was all of the snarkiness and sarcastic that was being thrown around. I'm all for a book that makes me giggle and laugh, but in my opinion Charley's "smartass" comments often went a little over the top. Additionally, I was getting a bit tired of all the references and comments about her carnal, sexual needs - way more information than I ever needed to know. 
 During some parts, I felt a little confused when Charley was talking about her past and things that had happened to her before the start of the story - I almost felt like there should have been a book before this one, almost like a prequel. But in the last couple of chapters, things became clearer about Charley's childhood - and I definitely identify with her: being misunderstood by family.
