She posted a photo of a memory stick shaped like a white horse. If you’ve done your research since the title reveal last March, you’ll know that lethal white is a syndrome in horses. Read about our summary of what we know about Lethal White so far here.

Going by dates from the publication of previous Strike books, Lethal White should be published in about six months time, which would be around September. However, as J.K. Rowling has mentioned on Twitter, Lethal White will be the longest book in the series so far, so perhaps the publication will be a little later than normal, unless the publishers work hard to try and get it out as early as possible. Let’s hope they do!

We hope everyone is as excited to read Lethal White as we are!
