Fifteen-year-old twins Briana and Hamish Ryan know they are descended from the medieval Welsh Princes of Powys and Deheubarth.
However, a trip to Wales begins to hint at an incredible secret in their thousand-year-old ancestry. A meeting with a mysterious stranger, who calls himself the Keeper of the Atlas, sets the twins on a desperate quest through time, connected to their ancient family history.
Swept up in events that challenge their sanity and courage, they soon find themselves fighting creatures they thought only existed in mythology.
