The Warlock Wandering - Christopher Stasheff

LOST IN TIME, FAR FROM HOME, SURROUNDED BY ENEMIES

Five hundred years from their own time and place on the magical planet Gramarye, Rod and Gwen Gallowglass are held captive on another planet at the edge of Terran civilization -- a world where purple-skinned, fur-kilted men challenge them in primitive battle.

But escaping this planet is only the first step - together, they must somehow flee all the way to Terra, wherein lies their only hope of returning to their own place and time.

Lost in a strange, foreign universe, pursued and hounded by their enemies at every turn, Rod and Gwen must race across the galaxy, fighting for their survival, their freedom, and to return home.
