Surf Monkeys

From publisher blurb: You're riding the surf off California, when you discover your friend Jorge has disappeared. The search for him leads to a gang of surfers called the Surf Monkeys. You expect they know more than they're letting on, but to find out for sure, you'll have to join their gang. Jorge's life may be in danger and every minute counts. Do you join the gang, or continue the search on your own?
