Escape from Hell is a fantasy novel written by Larry Niven and Jerry Pournelle. It is a sequel to Inferno, the 1976 Hugo Award- and Nebula Award-nominated book by the same authors. It was released on February 17, 2009.
The novel continues the story of deceased science fiction writer Allen Carpenter in his quest to help other damned souls in Hell. Like the first book, “Escape from Hell” extensively references Dante's Inferno. Jerry Pournelle, one of the book's co-authors, described the book as "Dante meets Vatican II."
