A Brave New World (слэш)

When the Dursleys are killed, Harry is left without legal guardians and is left prey to an ancient law that would see him owned by those who wish him harm. For his protection, he marries Severus and his new life begins as he embarks upon a marriage that is, for all intents and purposes, only for show, whilst he trains in a new magic that he soon discovers an affinity for.
