 This book blow me away. In the last few weeks I wasn't very lucky with liking what I read. The books I thought would be awesome I ended not liking, but not this one. To be honest, I picked this one because I thought it was a safe territory, angels/demons/magic/vampires what could possibly go wrong, at least I would kinda enjoy it and I needed to read a good book. I was so wrong, because you see, this book is amazing! I was really surprised by how much I enjoyed it, and yey, I finally got my happy surprise! 
 Amelie Bennett is a girl who is a Crossworld Demon slayer, a girl who seems to be on a first name basis with trouble and a girl who is destined to kill a guy she loves, according to the prophecy. When her instructors start disappearing and strange things begin to happen, there comes a new guy Jackson Smith-Hailey, who also happens to be her new trainer. Soon Amelie is suspected to be a big threat to the angelbloods and the whole city is hunting her. She has five days to find out who is killing the angelbloods, partnered with Jack she is set to find out the whole truth. 
 This book was thrilling and exciting from the very start and stayed that way until the end. There were so much twists and turns that had me guessing if something would happen even in the normal situations. Add to it a great writing with a lot of humor and already you've got a story made of awesome! The world building, the demons and vampires were described in so much detail that when you finish the book, you feel like those stuff are part of your everyday life. 
 I loved Amelie as a character, not only because she has my favorite name, but because she was a kickass, witty, sarcastic and a very tough character. While Jackson is your ultimate bad boy and I wanted to punch him more than a few times, he managed to win my heart. The chemistry between the two is amazing! From the first time they met, there were sparks between them (literally!). The constant bickering and snarky comments made me like them even more. 
 Overall, I loved this book and i can't wait to read the next book in the series. If you pick it up, I am sure you will not regret it.
