I remember being intrigued and curious about Sammael, AKA Sam, from the first book, Angel of Darkness. Like the first, neither character is very good or bad. Shades of gray this very much is. It seemed, at least for awhile, the one that was truly evil was consistently overlooked and allowed to go on and on.
I liked the twists and turns. Both characters I liked and had depth. Seline was a personal favorite. She started out ignorant, having not known she was being lied to, disliking herself. She comes full circle and I liked her growth throughout the book. Sam, what can I say? He was likable as well and he meet his match with Seline.
Az's book is next and I look forward to his as well.
