After reading Demon Angel I wasn't very excited about picking this one up. While Colin was an interesting character in the first novel, I wasn't keen on reading an entire book about him. Surprisingly, I ended up loving him.
Demon Moon is hard to explain, so I'm going to be lazy and copy/paste the backcover blurb here: No one would call vampire Colin Ames-Beaumont kind, but one would call him unnaturally beautiful. For two centuries his tainted blood has kept him isolated from other vampires, sustained only by his beauty and vanity -- bitter comforts. since a curse erased his mirror reflection, replacing it with a terrifying glimpse of Chaos.
Colin started off a bit annoying because he's narcissistic and cocky, but over the course of the story you really begin to see how much he values the few friendships he has. Those friendships are quite old though and Colin hasn't really tried to form new ones in a long time. This made watching him try to cultivate a relationship with Savi really fascinating.
Brook has a knack for writing characters who stand a little outside of human society because of their age or what they are. That gap between Colin and human society really came across in some scenes. But Savi was the character who stole the show. She's a computer genius who relies on her intelligence to get her out of the situations she finds herself in and this never wavered throughout the story. When the book opens, she's having a very James Bond-ish moment in an airplane that made me love her almost instantly. However, she has her limitations and she's aware of what they are. All in all, I really loved this installment of the series which turned out to be sweeter than I had anticipated.
