Jenny has no idea what it means when she stumbles through a magical “gate” at Stonehenge and travels back to the year 1347. She has no idea that the “old lady” who travels back with her is actually a sorceress protector, and a Guardian of the Gate. Most shocking of all, she has no idea that she has powers of her own just waiting to be discovered.
Gwenelda, the Guardian, intends to hide Jenny in the safety of a secret cave until the next time warp, but fate works against them, and Jenny is thrust into the society of the time. She disguises herself as a young man in order to protect herself, but when she discovers a sinister plot master-minded by a former Guardian named Rudigor, who has turned to the dark side—it becomes a race against time as Jenny tries to stop the sorcerer, and rush back to Stonehenge to get back to her own time.
