Spirit Totems — Christopher E. Long

When rich, pampered Jackson Brady decides to be a “normal” teen at summer camp, he and his pals Austin and Mazzy get more than they bargained for. Seeking shelter from a storm in a cave, they encounter a Ghost Shaman who teaches them to unleash their own animal spirit. It's a good thing, too, because they'll need those powers to fight a monstrous force that thirsts for revenge against humanity in this thrilling adventure that blends a coming-of-age story with dark fantasy.
