Changer

Wild, strange, and unpredictable, he is known as the the ultimate vagabond who slips in and out of myths and cultures, refusing to be pinned down to any one origin just as he refuses to be lcked into any one shape--or name. Yet when a quest for vengeance forces him to shed animal form and seek out King Arthur, the Changer discovers that the darkest of dangers threaten the timeless realm. For Arthur's sworn enemies have risen once more to topple the king and spread chaos among humankind. The Changer himself will be the enemy's unwitting accomplice, unless he somehow stops the dreaded forces and diabolical powers threatening to destroy Arthur's kingdom--and all humanity.
