The sweetest surprise is waiting for all those who thought they missed out the last train to Hogwarts. J.K. Rowling, the author of series of books about a young wizard, has kept her promise and ended the Harry Potter saga in the 7th book. However, it didn’t stop her from writing three e-books based in the world of Harry Potter. The first part of the new series, “Hogwarts: An Incomplete and Unreliable Guide”, is a mix of gossips and legends about the castle and its inhabitants, while “Short Stories from Hogwarts of Power, Politics and Pesky Poltergeists” reveals some of the dark secrets everyone was curious to hear. “Short Stories from Hogwarts of Heroism, Hardship and Dangerous Hobbies” is the last e-book from the mini-trilogy and concentrates on Hogwarts’ teachers. Although none of those short novels sounds like a particularly engaging lecture, there was some excitement in the air on the 6th of September, when the e-books got realised. The reason of that was a suggestion made by J.K. Rowling, the author, that she’s going to reveal some of the secrets in Sirius Black’s family tree, and that’s exactly what everyone was waiting for.
