Mason Coile is the pen name of bestselling author, Andrew Pyper. Mason writes books that are distinct from Andrew's: short, twisty thrillers with a sci-fi bent and a strand of horror in their DNA. Coile's first novel is WILLIAM, an A.I. ghost story. Both Mason and Andrew live in Toronto - in the same house! - which can get confusing sometimes.
