Update, August 18: This article has been amended to make it clear that not all of the stories in the new books have been written by Rowling, and that the majority of material in them is from the Pottermore archives. For more details, visit pottermore.com.

When Harry Potter and the Cursed Child was released, a small but hilarious subset of fans reacted with fury when they discovered that the “new Harry Potter book” was, as advertised, a screenplay by scriptwriter Jack Thorne.

These outraged readers – as well as more mild critics, who appreciated The Cursed Child for what it was but argued that it simply didn’t feel like JK Rowling – may be pacified by the release of three books set in the Harry Potter world.

Just to make things absolutely clear, some (although not all) of the writing in the new books, each of which will be a collection of short stories, is by Rowling. The books will be predominantly made up of material previously published on the Harry Potter website Pottermore, but two of the volumes will also contain unreleased stories by Rowling.
