"We have something Voldemort doesn't have. Twin power."
Cassia is the twin sister of Harry Potter. Following the murder of Lily and James, Cassia is taken to Ted and Andromeda Tonks, far away from Harry. 11 years later, the two are accepted at Hogwarts and meet, by chance, at Ollivander's, where the truth about them is finally revealed. At Hogwarts, Harry and Cassia discover much more than just magic and friendship. And what happens when a certain Hufflepuff boy takes a liking to her?
