Oyster, a streaming subscription service for ebooks, has added the complete Harry Potter series, including the seven main Harry Potter ebooks and three Hogwarts Library eBooks, to it’s quality library in a partnership with Pottermore. Oyster is the first and only place you can read every Harry Potter ebook–including the seven main books and the three Hogwarts Library books–in one place through your subscription.

To celebrate the partnership, Oyster has created an ebook reading experience that offers an unprecedented way to enjoy Harry Potter. Oyster’s Reader Themes will be replaced by “House Themes,” with designs inspired by Gryffindor, Slytherin, Ravenclaw and Hufflepuff, and readers can tap the Sorting Hat icon to have one chosen at random.

Oyster is also sending one lucky reader and a guest on a trip to Universal Orlando Resort to experience The Wizarding World of Harry Potter. Readers can find about more about entering the sweepstakes at oysterbooks.com/harrypotter
