Does anyone know if there will be a Monster High book 5?

I have Monster High, Monster High 2 The Ghoul পরবর্তি Door, Monster High 3 Where There's A Wolf, There's A Way, Monster High 4 Back And Deader Than Ever, and the Drop Dead Diary. I didn't see an add for Monster High 5 at the back of MH 4 and I'm worried there won't be another book.
