William and the Lost Spirit

William, the grandson of an elderly feudal lord in the thirteenth century, cant accept the death of his father. He thinks his new stepfather, Brifaut, must be an evil schemer. As the family prepares to move to a new home, his sister, Helise, disappears. Helise believes their father is trapped between this world and the next and needs her help and has set out across a countryside swarming with supposed bandits. William doubts her, but when his stepfather calls off the search for her, William makes the difficult choice to leave his mother and sneak away to find his sister. The journey becomes more and more strange and filled with magic, as they are joined by a mysterious nanny goat and an offbeat troubadour. Only when William is badly injured does he find a way between worlds. Eventually, he wakes beside his sister, and the two of them take on the ambitious Brifaut and discover the true murderer of their father.
