The island of Lundy is twelve-year-old Jenny's world. But soon she must go to boarding school on the mainland, leaving behind everything she loves, including Midnight, the wild stallion she has secretly befriended ...

Jenny has never lived away from the island, and her small world is about to become much larger. School is difficult to accept at first, particularly when she has Midnight's fate always gnawing at her mind. Jenny has much to come to terms with: her father's new partner, her own new friendships, and Midnight. Can it ever be right to take away a wild thing's freedom?
