An endorsement on the cover calls this YA book "a classic ghost story". I feel that is about as accurate a description as you can get.
A recently widowed father takes a position at an old manor house as head gardener. He and his two children live on the estate and the oldest child finds himself mixed up in the middle of a family curse that has claimed the lives of six children over the last two hundred years. Will he be able to prevent the seventh?
Ghosts, witches, ancient rites, a mystery and an old manor house. The story has all the ingredients!
