Somehow, I felt Marcus to be very young, and rather too naive -- therefore I wasn't quite impressed with him. He was a nice hero, though -- have quite a number of friends who's willing to help. Marcus also was in good relationship with his parents, which made this a rarity for me. In most of urban fantasy I read, parents are usually the problem (ha!). I liked the secondary characters, most notably Steve the Minotaur and Jones the drunk Oracle.
So will I continue book 2? We'll see...
