Good and evil fairy factions continue to battle over the fate of Elizabeth, daughter of Henry VIII, in this lighthearted, historically detailed third installment in the Scepter'd Isle series (after 2005's Ill Met by Moonlight
). To prevent the 14-year-old red-haired princess from ascending the throne, the Dark Sidhe, or Unseleighe, plan to destroy her benevolent Seleighe guardians, Lord Denoriel and his twin sister, Aleneil. Without them to guide her, Elizabeth might slip up, misbehave or marry—defeating the prophecy that she will one day rule England. But Denoriel and Aleneil's Dark Sidhe half-siblings, the twins Rhoslyn and Pasgen, shift their allegiances to help Denoriel and Aleniel keep Elizabeth safe and challenge the power of Vidal Dhu, prince of the Dark Sidhe. Lackey and Gellis blend the best of high fantasy with a grand dose of English history. (Feb.)
