Argh, frustrating story. Least favorite of all the Dark-Hunters in the series (I've read the first 10, this being 10). The story did have some interesting backstory on Acheron, Nick and Stryker, but not enough to read the book in my opinion. The main romance story was a bust. Heroine (Susan) was like nails on chalkboard who spoke mostly sarcastic comments. I really wanted someone to just slap her down, just once! The hero (Ravyn) was OK, but his tortured past was no different than any other Dark-Hunter. The romance was so unrealistic. I would classify this book as a 'wall banger'.
