The Tower stands in solitude. What began as a seventeenth-century manor house has grown over the centuries into something very different. Something evil. There are the stark walls, the shadow-filled rooms, the lonely corridors. But the Tower is haunted by much more than ghosts of the past, and it can do far more than simply terrify. It has a dark heart and it has grown restless. When five unsuspecting young people agree to stay there as house-sitters, they soon learn that visitors are not welcome in THE TOWER.
