Many aspiring authors look to big names like J.K. Rowling for the occasional writing tip. Today on Twitter, the Harry Potter author offered a little wisdom for those who don’t want any bad luck to hit their work.

While speaking on behalf of Robert Galbraith (the author she writes the Cormoran Strike series as), Rowling revealed on Twitter that her one writing superstition is that she never writes a book’s title page until she’s finished the book:

This appears to be Rowling’s one and only good luck charm in terms of making sure luck is on her side while writing any given book. We wonder how long she’s held this superstition for.

In other tweets this morning, Rowling, again speaking on Galbraith’s behalf, said that she/he is currently putting the final touches on the third Cormoran Strike novel.

So when will we know the title of the third Strike book?

The Cuckoo’s Calling and The Silkworm were published in the spring and summer of 2013 and 2014 respectively, so one could assume that the third book will arrive around that same time.

Rowling said last year that she has plans to write many more Cormoran Strike books. If you’re looking to enjoy more work by Rowling but haven’t picked up a Cormoran Strike book, now’s the time to settle in and do so. They’re really good.

Today’s life lesson from our favorite author: Don’t write your title page until your book is finished!
