On the long roads of Deverry ride two mercenaries whose fates like hidden deep in that of their own land. But Lord Rhodry, exiled from the dragon court of Aberwyn, has yet to discover his true parentage, and his swordmaster-lover, Jill, has barely glimpsed her awesome powers.

Meanwhile, the ancient sorcerer Nevyn, held back by his vows from boldly intervening in their lives, can only watch and wait as Rhodry and Jill move ever closer to danger. For as the two struggle to recover the Great Stone, the mystic jewel that guides the conscience of the kingship of Deverry, malevolent dark masters are weaving terrifying spells against them – and displacing messengers of death.
