Isla is a young fox whose world is shattered when her family suddenly vanishes. Isla must track them down, a search which will lead her to the Elders, a society of shape-shifting foxes, and to her own legacy as one of the world's most tormented creatures. The cold touch of humanity-known as the furless-is everywhere, with traps, dogs, and poisoned meats posing constant threats. Isla must outwit these perils with her flair for foxcraft: skills of cunning known only to foxes.
