Lexi never thought they'd come for her, she'd seen others been taken but didn't think it would be her turn, so trying to take her own life she gets distracted by her ring that her father gave her so she flees but she doesn't stand a chance. 
 She is taken to The Hole where everyone is branded depending on what sin they have committed, Lexi is branded blue for Lust so not off to a good start when this brings unwanted attention her way. But she is assigned Cole which from the start is just like any other guard but as time goes on she gets to see his caring side when Lexi is taking care of her dying friend, a thirteen year old girl in the hospital where she works as there relationship develops. After they witness the horrific deaths of a guard and a sinner who have fallen in love they do not want this to happen to them so a relationship is strictly off the cards. 
 I have to admit I was torn between the relationship with Cole and Lexi, as it was forbidden to have a relationship with a guard you feared for their lives and wanted them to end it but aahhh Cole how could she? 
 I just loved Zeus, Cole's crazy dog who also turns out to be Lexi's protector, he stole the show for me with his whackiness. 
 Overall I absolutely loved this book and I'm so pleased that I got the chance to read it. I could not put it down and would definitely recommend this book to everyone. Hopefully we won't have to wait too long for the next book.
