The novel tells the story of Jack Sawyer, a young boy who must travel from New Hampshire to California to save his mother, who is dying of cancer. Along the way, he learns of an alternate universe known as The Territories, where "twinners" (alternate versions of people from our own world) live. Jack must travel through both the U.S. and the Territories to find an object known as the Talisman, which he believes will save his mother's life.

Frank Marshall is producing the pic, and Michael Wright is executive producing. Boone previously directed The Fault in Our Stars, and has X-Men spinoff New Mutants due out April 13, 2018.

The Talisman development comes as projects based on King's works have become particularly hot, with Warner Bros.' It grossing more than $606 million worldwide to date and Netflix's Gerald's Game earning strong reviews. Sony's The Dark Tower stalled at the box office this summer, but there is a TV series in the works. Also on television, AT&T's Audience Network just renewed Mr. Mercedes for a second season, while Hulu has Castle Rock, a horror anthology based on King's works, set for 2018.
