In the Night Room is a 2004 horror-thriller novel by American author Peter Straub, a sequel to his 2003 book Lost Boy, Lost Girl. The work was first published in hardback on October 26, 2004 through Random House and it won the 2004 Bram Stoker Award for Novel. Straub encountered some difficulties while writing In the Night Room and had written several different passages for the work before growing bored with each version before writing it using the same technique he used for its predecessor in which he "reached down inside the book and turned it inside out."
