Jackaby is a fantasy detective story told through the voice of Abigail Rook. Abigail has just arrived in the United States from Europe in 1892. Like her anthropologist father she is well-educated, but is bored with her private boarding school life and is in search of adventure. Upon arriving in New England, Abigail has very little money with which to find a job or lodging. Finally, she happens upon an advertisement from R.F. Jackaby, resident PI of the small town of Fiddleham. But Jackaby isn't your normal private investigator. Abigail soon discovers that he has a keen eye for the extraordinary - including the ability to see supernatural beings. When Abigail accepts a job as the detective's assistant, she also inherits a ghostly neighbor, a man who has been turned into a mallard, and a third floor attic that looks and acts suspiciously like a woodland glade.
Her first day on the job, Abigail finds herself in the midst of a thrilling case: A serial killer is on the loose. The police are convinced it is an ordinary villain, but Jackaby is certain it's a nonhuman creature, whose existence the police deny. If you enjoy both mystery and fantasy, Jackaby may be a great next read. It has been nominated for the 2016-2017 Young Adult Golden Sower Award.
