Well Vol. 2 is the longest one, and its like a mystery. Its weird, sorta confusing plot. I thought it was pretty boring. It definitely has its moments though. D faces Dracu-... I mean his father in this one. That is all I will say.

Well the first novel is just classic, I love the characters in that one, but I would have to say Vol. 3 was my favorite. Once u get into the story u just cant put it down. Lots of cool action in it too. It is the complete opposite of Vol. 2.
