The Dogs of Winter by Kem Nunn (1997)

 This is the second surf noir novel I've read by Kem Nunn.  This one is set in way way Northern California.  It involves conflict between a group of surfers and members of a local tribe.  It's an interesting story.  You get a good sense of place, and the characters are interesting.  And it's well written.  This one is better than the other one.
