Two of a Kind (Harry Potter Fan Fic)

Two new students have transferred to Hogwarts, and both look almost exactly alike. Although, they claim to have no relation. The first is Pandora Blacksward, raised in the ways of muggles and wizards by her Squib aunt and her mother; the second of which refuses to practice magic for reasons few know. She is named for her box of secrets, stored inside her blood. Secrets she must keep at all costs, without even knowing them herself. The second, Alexandra Riddle. Voldemort's only know child, sent to gain the trust of Harry Potter and destroy the school from the inside. The success of the Dark Lord weighs on their shoulders, tipping one way or another due to their loyalties, and their loves.
