Book Burner is the fifth studio album by American grindcore band Pig Destroyer. It was released on October 22, 2012, through Relapse Records. The deluxe edition includes a short story by J.R. Hayes entitled "The Atheist" and an EP of hardcore punk covers. Vocalist J.R. Hayes stated that the band's only goal for Book Burner was "fast/brutal" and expressed happiness over the abundance of songs on the album with shorter lengths. Guitarist Scott Hull also affirmed that the band's goal was "shorter grind" on Book Burner in contrast with the preceding full-length album, Phantom Limb.
