Passion and betrayal in mythic Cornwall…. Mark, young king of Cornwall, faces heavy demands from Eire for tribute, and then his beloved sister runs away with a hot-headed knight. When, years later, her son Tristan returns unexpectedly to Cornwall, Mark hopes finally to oppose the outrageous Irish demands for tribute. Perhaps a royal marriage with Isolde, crown princess of Eire? But passion leads not to heavenly joy but rather to betrayal and deception. If Mark is to find true love, it must be where he least expects it.
