I wouldn't call Darkbound a great horror novel, but I don't know when I last enjoyed one as much. At 280-some pages, the plot clips along at a nice pace, and while I figured out some of the twists I still couldn't put it down until the very end.
The gore is very gory, but as detailed as it is, the author doesn't spend pages and pages spelling it out complete with the victim's every feeling of fear and pain. It doesn't have the richly endless bloodbaths of Clive Barker or the luxurious suffering-every-paper-cut detail of Stephen King, which is a plus for me. Normally I try to skim over those bits, and while you totally can here (it's easy to do--any important story bits you might miss will be explained later), I didn't find it necessary. YMMV.
It might've been a mistake to pick it up as bedtime reading, but it's great quick, light, delicious horror that's easy to digest in one sitting, and not so easy to forget.
