There is nothing special about Harry Potter – at least that’s what his Aunt Petunia always says. On his 11th birthday, a letter of admittance to Hogwarts School of Witchcraft and Wizardry opens up a hidden world for Harry: one of fun, friendship, and magic.

But with this new adventure comes great risk as Harry is forced to face a dangerous enemy from his past.
