Unity Series

A transdimensional anthropologist can't keep herself from interfering with Earth's darkest period of history in this brilliant science fiction debut. In medieval Italy, Niccolucio, a young Florentine Carthusian monk, leads a devout life until the Black Death kills all of his brothers, leaving him alone and filled with doubt. Habidah, an anthropologist from an alien world racked by plague, is overwhelmed by the suffering. Unable to maintain her neutrality, she saves Niccolucio from the brink of death.

The transdimensional empire, the Unity, has dissolved, its ruling powers forced into exile - but empires don't die easily. The living planarship Ways and Means has come to medieval Earth and ended the Black Death, but it keeps its intentions to itself. Someone is trying to kill its agent Osia, who is suffering through her own exile. Spy-turned-anthropologist Meloku becomes a target, too, when she catches Ways and Means concealing the extent of its meddling.
