The Anderson family inherits the Alba House estate in Scotland from a distant uncle. Upon moving there, strange things begin to happen.

Unexplained noises and smells, missing objects, bizarre phenomena in the forest and on the coast near the house. Thieves, or perhaps ghosts?

The children discover a hidden chamber and items from centuries past. Are they really alone in this house?

The heroes of the novel, both young and old, coexist between light and darkness and are connected through the ages by an old, hidden secret.
