A young apprentice hunter and her father journey to Ireland to help wipe out the last wolf pack. But everything changes when she befriends a free-spirited girl from a mysterious tribe rumored to transform into wolves by night.
Bounding with spirit with her lupine siblings through the impenetrable enchanted forest of 1650 Kilkenny, the young wolf-walker, Mebh, fears that the fragile treaty between humans and her pack is about to be broken. Troubled by her mother's unaccountable disappearance, and the rapid diminishing of her natural habitat, reluctantly, feral Mebh strikes up a friendship with rebellious, bright-eyed Robyn, unbeknownst to her that her father, Bill Goodfellowe, is a great English wolf-hunter. Now, appointed by the walled city's fiercely devout, wolf-hating Lord Protector, Bill has two short days to eradicate the wolf menace, and rid the neighbouring woods, the last stronghold of evil, of the savage beasts. But, free-spirited Robyn yearns to be free, and for the first time in a long while, she feels alive. Can she have the best of both worlds?
