Twilight Saga author Stephenie Meyer is to publish her second adult novel - a thriller about secret agents.
The Chemist tells the story of an ex-US government agent on the run who has to take on one last job.
Meyer's Twilight novels about teenager Bella Swan and vampire Edward Cullen, later turned into films starring Kristen Stewart and Robert Pattinson, sold 155 million copies.
Her last adult novel, The Host, was released in 2009.
'Brain as weapon'
Writing on her website, Meyer said she was "looking forward" to sharing The Chemist with her fans - once she had finished the editing process.
Publishers Little, Brown told Reuters that the book, released in November, tells the story of a "fierce and fascinating new heroine with a much specialized skill set".
