Sorcerer to the Crown by Zen ChoCall Number: Fic Cho, Zen
Born a slave, Zacharias Wythe has just been appointed England's new Sorcerer Royal -- much to the dismay of the socially conservative Royal Society of Unnatural Philosophers, who are already plotting to oust him from his post. But Zacharias has more urgent problems, including a dwindling national supply of magic and strained diplomatic relations with the Faerie realm. Unexpected assistance arrives in the form of fellow outsider Prunella Gentlewoman, an orphaned witch of uncertain origins and immense power. (Description from NoveList.)
