She just can't quit him! J.K. Rowling, who said she was done writing about Harry Potter, is set to release three short-story collections about the dark side of Harry, Time magazine reports. "Pottermore Presents" is a new series "that celebrates Hogwarts," and "delves even deeper into the wizarding world," according to Rowling's Pottermore website.

Each e-book is about 10,000 words long (a typical novel is closer to 100,000 words) and will sell for $3. They will be available beginning in September and can be preordered now.

In a statement to Time, Pottermore CEO said that Rowling will reveal "surprises and intricate details about several characters' lives."

The books' titles are "Power, Politics and Pesky Poltergeists"; "Heroism, Hardship and Dangerous Hobbies"; and "Hogwarts: An Incomplete and Unreliable Guide."
