The Thin Executioner is young adult and dark fantasy novel written by Irish playwright Darren O'Shaughnessy under the pen name of Darren Shan, published in April 2010. Inspired by and partially adapting Adventures of Huckleberry Finn by Mark Twain and The Firework-Maker's Daughter by Philip Pullman, Shan cited Middle Eastern influences for the novel's tone, describing the novel as his "favourite out of all his books [to have written]."
