As with her previous books, there will be no sex. The man she meets will just have to think pure thoughts until the end of the book.

Stephenie Meyer, the author behind the blockbuster Twilight saga, will release a new novel this November. Her publisher, Little Brown, announced on Tuesday that The Chemist, a “tautly plotted” spy thriller, will be released in the US (and presumably the UK) on 15 November. The Wall Street Journal was the first to report the news.

The Chemist represents a pivot for Meyer towards adult fiction, as this book will be her first to feature an adult protagonist. The main character is deliberately left unnamed in the publisher’s description, though a reference to her “unique talents” suggests that this book will remain firmly in the supernatural genre that Meyer as come to dominate:

She used to work for the US government, but very few people ever knew that. An expert in her field, she was one of the darkest secrets of an agency so clandestine it doesn’t even have a name. And when they decided she was a liability, they came for her without warning […]

When her former handler offers her a way out, she realizes it’s her only chance to erase the giant target on her back. But it means taking one last job for her ex-employers. To her horror, the information she acquires only makes her situation more dangerous.

Resolving to meet the threat head on, she prepares for the toughest fight of her life, but finds herself falling for a man who can only complicate her likelihood of survival. As she sees her choices being rapidly whittled down, she must apply her unique talents in ways she never dreamed of.

Meyer’s Twilight trilogy followed the saga of American teenager Bella Swan as she met and fell in love with a vampire, Edward Cullen. The books became a pop-culture phenomenon, selling in excess of a hundred million copies worldwide and inspiring film adaptations starring Kristen Stewart and Robert Pattinson.

Her 2008 standalone novel about aliens, The Host, also sold well, though the movie version, starring Saoirse Ronan, was a comparative flop, earning only $64m worldwide compared with over $500m for the last instalment of the Twilight movies.
