Reminiscent of Doll Bones and Small Spaces, this "delightfully eerie" (Erin A. Craig, New York Times bestselling author of House of Salt and Sorrows) middle grade novel tells the story of a girl who must rescue her aunt by entering a world of ghosts, witches, and monsters to play a game with deadly consequences. Evie Von Rathe lives in Blight Harbor--the seventh-most haunted town in America--with her Aunt Desdemona, the local paranormal expert. Des doesn't have many rules except one: Stay out of the abandoned slaughterhouse at the edge of town. But when her aunt disappears into the building, Evie goes searching for her. There she meets The Clackity, a creature who lives in the shadows and seams of the slaughterhouse. The Clackity makes a deal with Evie to help get Des back in exchange for the ghost of John Jeffrey Pope, a serial killer who stalked Blight Harbor a hundred years earlier. Evie reluctantly embarks on a journey into a strange otherworld filled with hungry witches, penny-eyed ghosts, and a memory-thief, all while being pursued by a dead man whose only goal is to add Evie to his collection of lost souls. Will she ever find Des, or is The Clackity planning something far more sinister?
