R.U. Ginns lives in a building close to a bridge, just outside of a major American city. He collects books, graphic novels, take-out menus, and old catalogs, and spends countless hours sifting through them, trying to decide which things are made up, and which are real. He knows that the more horrible and scary a story is, the greater the chance that it is one hundred percent true. He is NOT related to Russell Ginns, who is the author of the Samantha Spinner adventure series and Puzzlooies puzzle-story books.

Javier Espila is a Spanish illustrator who has been devouring cartoons ever since he was old enough to sit upright in front of the TV. This had the unfortunate consequence of causing serious inflammation of the brain, rendering him unsuitable for any job that required him to lift anything heavier than a pencil. In recent years, his condition has deteriorated, and he is now forced to write absurd and fantastic stories to alleviate the constant pressure on his skull.He lives with his wife and his two daughters, who help him by alternating cartoons with video games.
