Professor William Shivering lives in a house by the sea with three cats and a one-eyed raven named Glinda. When he's not writing true stories about fake worlds, he enjoys walking the cliffs and conversing with the moon. He's the president and founder of CASPR (Coalition for the Appreciation of Shades, Phantasms, and Revenants), a non-profit that provides assistance to disembodied peoples. Professor Shivering employs an assistant, Newbery Honor winner Christian McKay Heidicker, though he seldom if ever takes Christian's writing suggestions. Mr. Shivering is rarely cold.

Christian McKay Heidicker reads and writes and drinks tea. Between his demon-hunting cat and his fiddling, red-headed girlfriend, he feels completely protected from evil spirits. Christian is the author of Scary Stories for Young Foxes (a Newbery Honor book), Cure for the Common Universe, and Attack of the 50 Foot Wallflower and the co-author (with William Shivering) of Thieves of Weirdwood. He lives in Salt Lake City, Utah.
