Sanctum  - Sarah Fine

I really liked this imaginative story.  This is unlike anything that I have ever read, and in a good way.  It has a kick-ass heroine and a very likable hero.  Even if his name (Malachi) makes me remember Children of the Corn.  (That movie gave me nightmares) About half way through I got over that.  I hope the second book doesn't disappoint me.
