Long, long ago in Deverry, Lillorigga, daughter of the Boar clan and cousin to the child-king, becomes enmeshed in the increasingly sinister politics at the palace of Dun Deverry. Not least among the plotters is Lilli's own mother, the enchantress Merodda. Lilli has inherited Merodda's powers, but not her taste for power. When Merodda orders the death of Lilli's foster mother, Bevyan, Lilli leaves Deverry swearing revenge. Her actions will have consequences not only in her time, but also in generations to come, as those who die are reincarnated.
