Harry Potter fans get two new surprises from J.K. Rowling

Wizards, witches and Muggles, rejoice: Harry Potter Book Night is going worldwide in 2016, and J.K. Rowling has revealed new secrets about the Dursleys.

The Dursley details were revealed by Rowling on Pottermore on June 23, Dudley Dursley’s birthday. On Pottermore, Rowling shared the backstory of Vernon and Petunia Dursley, Harry’s aunt and uncle, their (strained) relationship with his parents and why they hated him.

Meanwhile, Harry Potter Book Night is going global, U.K. publisher Bloomsbury Children’s Books has announced. (In the U.S., the Harry Potter series is published by Scholastic). The celebration will take place Feb. 4.
