Mason's Haunted Castle

Twelve-year-old Mason Jones is excited that his family inherited Uncle Thomas's castle. They are invited to spend the weekend at the castle in Nottingham.

Uncle Thomas's castle is haunted, and Mason has an encounter with the realm of wandering spirits. Mason meets one of the ghosts, named Roary, a prince from long ago. He was murdered when he was twelve and wants Mason to help him solve the mystery. The caretaker of the castle tells them of an ancient journal that might hold all the secrets of the castle, but it is hidden somewhere in the castle.

As they look for the journal, they find they have spirit enemies that try to stop them from finding the journal. Roary's Uncle Edward comes to take over the castle even though he is a ghost and a wizard. Mason is now caught in a big ghostly family feud, and Roary won't let his uncle have his way. Mason's help to Roary becomes more determined than ever to solve all the mysteries.
