J.K. Rowling confirmed over Twitter that she’s working on two new novels, in addition to the four Fantastic Beasts movie sequels she’s penning. This first tweet is in response to a fan asking when she’ll deliver another book:

I’m working on it (literally). And thank you! https://t.co/vA6CZcVhRW

When another fan claimed she would write books to accompany the Beasts films about the adventures of Newt Scamander, Rowling gently corrected:

No, no, no. There won’t be Newt Scamander novels. Only movies. Calm down, there! https://t.co/Zyhim6Wscd

Rowling, who has also written crime novels under the pseudonym Robert Galbraith, admitted that one of her upcoming two new projects will be a Galbraith thriller, responding to a fan asking which name the new work would be out under:

One of each, but I’m not sure which will come out first. I’ll let you know as soon as I do! https://t.co/gFF8UZmq5W

No word yet about the subject matter of Rowling’s new stories, but if her past body of work is any indication, it could truly be anything.
