Dekker, all the way. I really like The Oath by Peretti, and the "Present Darkness Series", but I like Dekker's style better I think. A little more fast-paced. I'm currently reading Skin, which I've heard wasn't that good, but I got it on bargain sale at Barnes and Noble for like 5 bucks. So, I'm reading that until I get his next book, ADAM, which is supposed to be his best book yet according to the advance reviews I've read.
