All is not well in Brightsbane, the village of eternal night. An evil wizard-the very wizard who swallowed the sun, in fact-has stolen The Boneyard Compendium, a book of powerful spells that could bring about the destruction of the entire town. When an Elder enlists the orphans of St. Crippleback's Home for Waifs and Strays to help track down the wizard, the ever-intrepid Mabel Gray sets out to find the three keys of bone that unlock the Compendium before the wizard gets his diabolical hands on them. Armed with only her wit and a frightfully small bit of magic in her pocket, Mabel embarks on an adventure that brings her face-to-face with talking scarecrows, high-ranking monsters, babbling witches, ill-tempered daemons, a riddlesome owl who fancies himself a raven, and more. But the wizard isn't a wizard for nothing, and his evil magic may prove to be more powerful than Mabel ever imagined...
