Devil's Kiss is dark and gritty. And not a happy book. It's about struggle, and fight, and sacrifice. And loss. But with sweet moments, too. I thought the beginning of the book could have used more build up though, so that when they revealed something it was more of a shock and a blow. The big fights near the end were great, although I won't forgive what happens to my favorite character. It ends in a way where it could be left as a standalone, but I'm still looking forward to book 2. I'd like to see how Billi deals with the ending of book 1, and hopefully get a happier ending.
