Bag of Bones is a 1998 novel by Stephen King.
 It focuses on an author who suffers severe writer's block and delusions at an isolated lake house four years after the death of his wife.
 It won the Bram Stoker Award for Best Novel in 1998, and the British Fantasy Award for Best Novel in 1999.
 The book re-uses many basic plot elements of Daphne du Maurier's "Rebecca", which is directly referenced several times in the book's opening pages; however, the relation of these elements (including a wife who is dead as the book opens, her posthumous effect on future romance, a drowning, and house haunted by the memories of previous inhabitants) to the plot and characters is markedly different.
 When the paperback edition of "Bag of Bones" was published by Pocket Books on June 1, 1999 (ISBN  ), it included a new author's note at the end of the book, in which Stephen King describes his initial three-book deal with Scribner ("Bag of Bones", "", and a collection of short stories titled "One Headlight", which later became "Everything's Eventual"), and devotes most of the piece describing the origins of the then-forthcoming "Hearts in Atlantis".
