Ill Met by Moonlight (The Doubled Edge, Book 2)

Sixteenth century England: a nation at a fatal fork in time, leading to two possible futures. Either an evil queen will join with the Inquisition and rule with a blood-spattered iron hand - or a benevolent queen named Elizabeth will rule wisely and well. But the evil Unseleighe Sidhe are determined that the little girl Elizabeth shall never grow up to take the throne. Opposing them are the good Sidhe of elfland, including Denoriel, who has already foiled one attempt against Elizabeth, almost at the cost of his own life. But a few years have passed, and Denoriel still guards the young princess, now eight years old, secure in the knowledge that Vidal, leader of the evil Unseleighe, is dead. Unfortunately, he is wrong. Vidal was wounded almost fatally, but now his recovery is complete and he has set in motion a plan to bring about a new dark age of which Denoriel is dangerously unaware...
