Thom Woodmen, a bigfoot or Oh Mah, who lives in a human world, is bonded to Ben Steele, an average teenager. Thom has barely adjusted to his new status as a Guardian when he discovers others working against him and there's a price on his head. Then an intruder appears in his family’s territory, and he senses strange energies coming from Ben.
While they struggle to find out who wants Thom dead, Ben is tested to confirm Thom’s suspicions—Ben has magic. Ben shows promise, but he just wants to stay the normal human within their group of friends. After more attacks, Ben begins to see how magic might help him protect Thom—if only he can learn enough before the witch who is hunting them closes in for the kill.
