Fleeing to a secluded Minnesota cabin after an ugly divorce, Lindy Anderson has sworn off men- until she finds a wounded naked man sprawled on her porch. Reluctantly taking him in, she discovers an ancient secret: Gareth is a Bearwalker, a shapeshifter able to exist as a human or a bear. His legendary clan has been hiding deep in the wilderness, safe from humankind. But now someone has learned of their existence and wants them dead.

As Lindy is drawn into Gareth's secretive clan and vows to help save them from the humans who threaten their survival, she finds herself falling in love with the clan's powerful Guardian. But Marin has taken his own vow to protect his people from all humans, even her, and even at the most terrible of costs.

Their fates now entwined, all three must risk their lives-- and hearts--if the Bearwalkers are to survive.
