Harry Potter and the Sorcerers Stone (Philosopher's Stone) is the first book in the series of 4. (Like I said before, there will be a total of 7) It's about 309 pages long and incredibly fun to read.

He knows no spells, has never helped hatch a dragon, and has never worn a cloak of invisibility.

Harry's room is a tiny closet at the foot of the stairs, and he hasn't had a birthday party in eleven years. But all that is about to change when a mysterious letter arrives by owl messenger: a letter with an invitation to an incredible place that Harry's destiny that's been waiting for him...
