Title: Rosemary and Rue
By: McGuire, Seanan
Call #: Science Fiction McGui.S
First in the ongoing “October Daye” series, but the world-building and story are fully fleshed out in this novel. McGuire has an encyclopedic knowledge of fairy tales (the dark, un-Disney-fied kind) and folk lore, and they all come out to play here. Your heroine is a half-fey, half-human changeling who just spent the better part of a decade cursed to live as a fish, so she has a few issues. She also has a murder to solve and fairy court politics to navigate. A rich world with terrific characters that just keep getting better!
