Orphaned Harry Potter has no idea how famous he is until he turns 11 and receives his invitation to attend Hogwarts School of Witchcraft and Wizardry, opening up a whole world of magic and muggles, potions and spells, friends and enemies. The series is now available in ebook form--which makes it a lot easier to take a whole boxed set on vacation. Starting June 19, Amazon Prime members can borrow Harry Potter books for free from the Kindle lending library, (though borrowing is limited to one book a month at this time).
