“Sherlock Holmes crossed with Buffy the Vampire Slayer.” —Chicago Tribune Newly arrived in New Fiddleham, New England, 1892, and in need of a job, Abigail Rook meets R. F. Jackaby, an investigator of the unexplained with a keen eye for the extraordinary--including the ability to see supernatural beings. Abigail has a gift for noticing ordinary but important details, which makes her perfect for the position of Jackaby’s assistant. On her first day, Abigail finds herself in the midst of a thrilling case: A serial killer is on the loose. The police are convinced it’s an ordinary villain, but Jackaby is certain the foul deeds are the work of the kind of creature whose very existence the local authorities--with the exception of a handsome young detective named Charlie Cane--seem adamant to deny. “The rich world of this debut demands sequels.” —Kirkus Reviews, starred review “We honestly couldn’t put it down.” —Nerdist.com “Toss together an alternate 19th-century New England city, a strong tradition of Sherlockian pastiche, and one seriously ugly hat, and this lighthearted and assured debut emerges, all action and quirk.” —Publishers Weekly • A Top Ten Fall ’14 Kids’ Indie Next Pick • A 2014 Kirkus Reviews Best Book for Young Adults • A 2015 YALSA Top Ten Best Fiction for Young Adults Title • A 2015 Pacific Northwest Book Award Winner • A 2015–2016 Georgia Peach Award Nominee • A Junior Library Guild Selection
