Okay, I finished it. Actually I finished it late that night the first time I posted.
This book is so much fun. The person who handed it to me said, "Here. It's Twilight, with vampires." I am here to tell you it is not. Yes, there's a doomed-love-with-a-monster kind of scenario. And it has all the must keep reading adventure and make your heart flutter romance. But it's like the antidote to Twilight. All the characters are likable, the romance is on equal terms between two solid characters, and, my favorite part: it ends! None of the usual YA leave you hanging wait for book 2. How nice to read a book that keeps you on your toes and then actually satisfies at the end.
Because I always think a good review mentions the downsides (stop reading, Maggie), I will say that the MC's BFF annoyed me; I think it's possible she was supposed to be annoying, but still. This, however, is a minor point. Also, I'd add that there is sex. Good, clean, totally consensual and healthy sex, but it may affect to whom you recommend the book.
My 16 year-old cousin is going to flip when I send it to her.
