The Potter Twins and the Sorcerer's Stone

Harry and Callista Potter have never been the stars of a Quidditch team, scoring points while riding a broom far above the ground. They know no spells, have never helped to hatch a dragon, and they have never worn a cloak of invisibility.

All the twins know is a miserable life with the Dursleys, their horrible aunt and uncle, and their abominable son, Dudley-- a great big swollen spoiled bully. Harry's room is a tiny closet at the foot of the stairs, Callista's room isn't much better, being an old, dusty, and moldy couch in the attic crawlspace, and both the twins haven't had a birthday party in 10 years.

But all of that is about to change when two mysterious letters arrive by owl messenger; letters with invitations to an incredible place that Harry and Callista-- and anyone that reads about the twins -- will find unforgettable.
For it's there that the twins not only find friends, aerial sports, and magic in everything from classes to meals, but a great destiny that's been waiting for them... If Harry and Callista can survive the encounter.
