Mick Oberon may look like just another 1930s private detective, but beneath the fedora and the overcoat, he's got pointy ears and he's packing a wand. Among the last in a line of aristocratic Fae, Mick turned his back on his kind and their Court a long time ago. But when he's hired to find a gangster's daughter sixteen years after she was replaced with a changeling, the trail leads Mick from Chicago's criminal underworld to the hidden Otherworld, where he'll have to wade through Fae politics and mob power struggles to find the kidnapper and solve the case.
