In the World of the Three Moons, an unknown evil stirs...and severe earthquakes, widespread volcanic eruptions, and disastrous weather rock the land...

Only the legendary Sky Trillium -- made from the three talismans of the princesses Kadiya, Anigel, and Haramis -- can heal the ancient wounds of the world. But Anigel's is missing, and Kadiya's talisman has lost its potency. Yet even if the sisters are able to regain all three of the talismans, will they be strong enough to control the awesome magic of the Sky Trillium?

Encounter the wondrous world of the Black Trillium, originally created by three of fantasy's stellar talents: Julian May, Andre Norton, and Marion Zimmer Bradley.
