A woman trapped in the body of a deer. A dark sorcerer in relentless pursuit. A mysterious child, found alone on the slopes of a great mountain.

This is the turbulent and heartbreaking story of Sive, a girl of the Otherworld who must flee her world of plenty to live as a hunted beast. Surviving hardship, danger and crushing loneliness, she finally finds refuge—and unexpected joy—with a mortal champion, Finn Mac Cumhail, the great hero of Irish legend. But Sive's ordeal is far from over. She has a gift the Dark Man craves, and the smallest misstep will give him his chance to snatch her away from all she holds dear.

Set in the wild, magical landscape of Iron Age Ireland, Shapeshifter is a tale of rapacious evil, quiet courage and the healing power of love.
