Gutter Mage

"In a kingdom where magic fuels everything from street lamps to horseless carriages, the mage guilds of Penador wield power equal to the king himself. So when Lord Edmund's infant son is kidnapped by the ruthless Alath Guild, he turns to the one person who's feared by even the most magically adept: Rosalind Featherstone, a.k.a. the Gutter Mage. But as Roz delves into the circumstances behind the child's disappearance, she uncovers an old enemy from her traumatic past and a long-brewing plot that could lead to the death of countless innocents, as well as the complete collapse of Penadorian society itself!"--Jacket flap.
