Black Unicorn

From Publishers Weekly Tanaquil, whose only talent is the ability to fix things, lives in the isolated desert palace of her mother, the sorceress Jaive. When an inquisitive peeve--one of the palace pets--unearths a cache of strange, sparkling bones, Tanaquil uses them to piece together a unicorn's skeleton. A stray blast of Jaive's magic brings the creature to life, and it escapes to the desert, followed by Tanaquil and the peeve.
