Isabella has finally returned from Earth-14 on Percy Jackson's earth. But before she can really start school in her world again, the Multiverse has sent her on another mission. A year-long mission at that. (Of course, most time on her earth and on Earth-14 will stop until she finishes.) With the ultimate urge to survive for Percy and her family, what will happen on Earth-20, London England, 1991 when she must attend Hogwarts, in a class of kids almost two years younger than her, now being the oldest in her class instead of being one of the youngest like she always has been? What will happen when she meets Harry, Hermione, and Ron? Will she be able to escape this world, or will she find new friends? Find out by reading Warped: The Sorcerer's Stone.
