I really wanted to like this one, I love the cover and was intrigued by the blurb but having forced my way through the first 100 pages I've had to admit defeat. I can't connect with Serafina and as the story is told first person from her POV it doesn't help that I hate her voice. She comes across as so naive & I can't for the life of me figure out what she sees in Marcus that would make him worth risking her wings for. I can't believe an angel who is thousands of years old would be quite as stupid as she was to sign that contract either.
I don't think there is anything wrong with the way the book is written though so don't let me put you off trying it. Unfortunately it just isn't for me so it's a DNF I'm afraid :-(
