Her mother's will states that Summer's legal guardian is her uncle Tristan: a man Summer has never even heard of before. Forced to leave her life in London, Summer moves to Tristan's creepy, ancient house in Cornwall. There she is met with indifference from him, open hostility from her cousin, and an aunt who has chosen to leave rather than to tolerate her presence.
Soon Summer comes to believe that the house may be haunted. But is it haunted by ghosts, or by the shadows of her family's past?
Scared and lonely, Summer begins to spend more and more time in the beautiful sheltered cove she discovers nearby. But she's not alone. A local boy frequents it too. Can Summer find first love and the answers to the mysteries of her new home with this good-looking boy who appears to be too perfect to be true?
