When Olympic ski champion, Sean Wilson, takes his best friend's widow, museum curator, Paige Wellington, on a vacation to The Grand Canyon, he's attracted to more than the beauty of his companion and the magnificent scenery. Sean discovers an entire pack of werewolves thriving in a canyon paradise. The Havasupai, known as the people of the blue-green waters, share his genetic defect, the werewolf gene. Paige learns the secret of the wolf tribe and struggles with her decision to end their relationship, unable to imagine herself married to a half-man, half-wolf creature and bear his fuzzy, carnivorous children. Sean wars against the beast within. Even as the werewolf, he is an intelligent and keen animal, never losing touch with the man lurking beneath the fur and never losing sight of the woman he loves. Will the wolf gene keep them together or tear them apart?
