Raven Castle

When Kaat hears that she will have to spend her summer vacation at her aunt and uncle's horse stud farm, she is not happy about it. She would much rather have gone with her parents on their expedition to the Middle East. But when she first sees the haunted castle located near the farm, she becomes curious. When she and her cousin Eva discover the body of a young man not far from the castle and find a secret document about the castle, Kaat knows her vacation will be more adventurous than expected.

Kaat and Eva go to investigate. What lurks in the mysterious castle, of which only the tower is still intact? A ghost, or is there more going on? Soon the girls realize they have landed in a dangerous situation. Only ingenuity and coolness can save them from this. Will they succeed in unlocking the secret of the castle?
