One thing I didn't like about this book was the romance, one minute Cas is saying how he's going to kill Anna and then the next minute he loves her! Okay so I get that feelings develop when you learn more about a person. But Anna is a ghost and he is a human which somehow doesn't work, they're doomed from the start so its not exactly going to work for them. It was cute how Cas was the only person she could truly be calm around before she got set free and I did like seeing how he always made sure that she was alright.
Overall I really enjoyed this book, the pacing of it was great as there was never a dull moment that dragged on. The plot line was clever and kept me on the edge throughout the whole of the book, I felt nervous for the characters a lot of the time. I actually liked the horror aspect to the book especially as Kendare Blake hasn't held back in some parts which you'd expect a YA author to do. I recommend this book to anyone who is interested in paranormal YA or if your someone who is looking for something thats slightly gruesome in some parts, this is the book for you!
