'Fifty Shades of Grey' author announces new Christian Grey book

Author EL James has announced Darker: Fifty Shades Darker as Told by Christian, a new book that retells her previous erotic story from a different perspective.

Set for release in November, it'll retell her 2012 novel from the point of view of the titular billionaire, rather than his submissive partner Anastasia Steele.

"I do hope you enjoy it," James said in an Instagram post.

The Fifty Shades franchise, which began as 'mommy porn' Twilight fan-fiction, went on to make James the fastest-selling author in history. It also spawned a film trilogy, with the two movies released so far making collectively more than $NZ1 billion at the global box office.

This is the second time that James has rewritten a novel from the franchise after 2015's Grey: Fifty Shades of Grey as Told by Christian.

Like every book and film in the series, it was savaged by critics but enjoyed significant commercial success.
