OMG, Kitty and the Midnight Hour! I read the first two or three books years ago and could not for the life of me remember the title, and it's been bugging me for months now. So glad you mentioned it! And yes, Cormac/Kitty = awesome.

I wish that I had read the Percy Jackson books more slowly; aside from the first one, all the others blend together for me. IIRC, the last two books were the best. The fight scenes just got more and more amazing.
