Book I Could Not Put Down

"Gideon's Dawn" by Michael Warden
It's about this semi psychotic grad student, i think geophysics and seismology, he's had a very nasty childhood that he represses but comes out in dreams (he kills and mutilates squirrels while in a sort of unconscious state and did his damnedest to gut himself once) but anyway he is out in the field in the Rockies and weird things start happening and he gets transported to another world (sort of) and the people there think he's their Kinsman Redeemer, sort of like Jesus.

the book was... grotesque, i suppose you could call it, but it was fascinating, the cultures, the parallels to Christianity, the fantasy... all very cool. i actually haven't read it in a while, should do that.
