HP: Bound to the Strongest Wizard Training System

On her eleventh birthday, Till receives her acceptance letter from Hogwarts—and is instantly bound to the Ultimate Wizard Training System! ***Synopsis fails, but the story delivers guaranteed fun. CP: Severus Snape. The author swears: no torturing the heroine, and no torturing the hero either. Heavy OOC. The general world-building and settings follow the original, but for the sake of the plot, major deviations from canon are in play. Contains GGAD content. No breaking of canon couples, but canonically single characters may be given original love interests.
