This is the 4th book in JR Wards Fallen Angel series. I love this series and I loved Rapture. 
 This book was about Matthias who was an XOps boss. If you've read the other 3 books you'll remember him as an evil, soulless, douchbag. Like me you probably didn't like him in the other books, but he redeems himself in this book after he gets hit by a car and meets Mel's Carmichael. 
 Mel's is a reporter for the CCJ and after she hits Matthias with her car on the way home one night her life completely changes. She finds herself drawn to Matthias even though he has amnesia and remembers nothing from his past. As things start to fall into place for Mel's she finds herself questioning Matthias and what she believes. 
 This is a great book that you'll not want to put down!
