Princess Sabina has always obeyed her father, King Norwen. But when he plans to marry her to a ruthless prince, she runs away. Soon captured, she's thrown into a tower cell to await her punishment.

The prison is already occupied — by a terrifying ghost. Hiding her fears, she befriends him, hoping they might help each other. As they grow close, she realizes he's not a phantom but an enchanted mortal who remembers nothing of his past. Physical contact with Sabina is the key to bringing back the memory of the man she learns is named Killian. The more intimate they become, the more he remembers.

Their shared adversity forges a bond between them, but will they be free to acknowledge their love for each other, or will her ruthless father capture her and drag her away from the man she's coming to love?
