Stephenie Meyer is once again writing in the daylight! The author, best known for her astronomically popular young-adult series Twilight, will be moving away from the teen demographic to release a new spy thriller for adults called The Chemist on November 15. (She previously released another non-Twilight novel, the adult sci-fi book The Host, in 2008.) The novel will revolve around a female ex-operative forced to go on the run from the U.S. government, which fears she knows too much about a highly classified operation. “The Chemist is the love child created from the union of my romantic sensibilities and my obsession with Jason Bourne/Aaron Cross,” Meyer said in a statement. “I very much enjoyed spending time with a different kind of action hero, one whose primary weapon isn’t a gun or a knife or bulging muscles, but rather her brain.” So, let the guessing game begin: Which actress is going to play her in the inevitable film adaptation?
