'Harry Potter' comes to Oyster's all-you-can-read book service

If you're the sort of Harry Potter fan who can't help but read the series again and again, Oyster has a treat in store. The all-you-can-read subscription service has teamed up with Pottermore to carry all of the Harry Potter books, including the Hogwarts Library collection. There's even a little treat the first time you start reading -- rather than pick from one of the humdrum standard themes, you choose your favorite Hogwarts house (Slytherin, obviously). You probably don't want to sign up for Oyster's $10 a month service just for the sake of reliving Harry's school years, but it's potentially cheaper than purchasing the series on top of a slew of other books.
