Even witches have to retire from magic sometime. When Peter, Jennifer, and their four-year-old sister, Molly, visit the Eventide Home, they find just what their gran promised: a coven of kindhearted, retired old witches. But on the heels of their visit, the children themselves are visited--by a Pictish girl fleeing a massacre more than a thousand years earlier. Evil forces are hunting the Pictish child, forces that have tracked her across centuries, bent on fulfilling the dark designs of a single mysterious person in the Eventide Home.
