I absolutely loved this book. I think the characters were very well rounded and the plot was extremely interesting. I literally could not put this book down. 
 Anna, the main protagonist of this story, is a teenager who was born with a sixth sense to see and feel others emotions, among other special abilities involving her senses. She is aware of a struggle battling within her that pulls her towards danger and has a particular pull towards drugs and alcohol. But ultimately her good side wins the inside struggle she faces. She has no idea why she's the way she is until she comes across bad boy, Kaiden Rowe, who seems to share her special abilities. 
 Kaiden is Anna's complete opposite, he leads the ultimate bad boy life, being a drummer in a band, he gets to lead the life of sex, drugs, and rock and roll but mainly sex. But something about Anna catches his attention making him question his life and gives him hope. 
 You find out that they are a race called Nephilim, children born from demons and raised to carry on their fathers work. Anna is the daughter of Belial (demon of substance abuse) hence her draw towards drugs and alcohol but there is also something special about Anna being that her mother was an Angel. She was raised by her adoptive mom Patti, who kept her secret up until her sixteenth birthday after meeting Kaiden and learning about her special gift. Patti then tells Anna about the nun who adopted her out and how she was supposed to meet with her and she was too meet her father. From there they planned to save up money to make the trip and she is also sworn to not see Kaiden because of the danger he puts her in. But of course she is drawn to him. 
 She goes to see him and finds out that he is the son of Pharzuph (demon of lust) which puts things in perspective about Kai. He then takes her home and finds out about the trip they planned and offers to take Anna. For good reasons Patti agrees to this and they are on there way the next day. 
 The trip is next butttt you will have to read the book and find out for yourself how that goes. Trust me you will not regret picking this book up. ;)
