The Estranged Star

AU: Millions and more dream of living in the Harry Potter books and going to Hogwarts. Of course, it's all fun and games until you have to face down Tom Riddle, deal with annoying Hufflepuffs, live with the Malfoys, screw up canon, and what might be the worst: be reborn as Bellatrix Lestrange's son.
