Seth Roberts is a typical teenager, that is, until his mother sends him to St. John's, Newfoundland, Canada, to visit his Great Uncle Herman. In St. John's, Seth discovers that Herman is a wizard, in fact, the son of Merlin himself. Shortly, Herman asks Seth if he would like to go on an adventure and he quickly agrees. With the help of a strange medallion, Herman sends Seth back in time to the year 1128 A.D. to Cambria, a village founded by Tristan, one of the Knights of Author's Round Table. In Cambria, Seth meets his father and discovers his true potential, family secrets, and love. Soon, Seth finds himself on the adventure of a lifetime as he races to save Briana, the queen of Cambia, and Cambria itself.
