Now you can read two of Harry Potter's Hogwarts textbooks--Quidditch Through the Ages and Fantastic Beasts and Where to Find Them, penned by J.K. Rowling herself under two delightful noms de plume. All proceeds from the sale of these 64-page paperbacks are being donated to Comic Relief, an organization which "exists to tackle poverty and promote social justice by helping disadvantaged people in the UK and Africa to realize their aspirations and potential."

Quidditch Through the Ages--charmingly reproduced as if it were a facsimile of the copy from Hogwarts School of Witchcraft and Wizardry--starts with the history of broomsticks, describes the evolution of Quidditch through the generations, and includes the rules of the game as well as a chapter on modern-day play. Fantastic Beasts and Where to Find Them is the most complete A to Z listing of magical beasts that exists, and includes their classifications. From Basiliks to Jarveys to Werewolves, this book covers all the magical beasts you've only heard of and will introduce you to a host of new ones you haven't.
