Gwendy's Button Box is a horror novella by American writers Stephen King and Richard Chizmar.

The French edition, released by Le Livre de Poche in September 2018, reproduced those illustrations with brand new ones by the same artist.

Twelve-year-old Gwendy Peterson encounters a stranger in dark clothes and a black hat who invites her to "palaver."

"I had a story I couldn't finish, and [Chizmar] showed me the way home with style and panache," King said in a statement.
