Double Duel Dine

Total OC! Main character is mine. Marcus Dine has never been courageous, he has never been ambitious, he has never been clever, but what he has always been is loving and kind. When he arrives to Hogwarts wounds are reopened, enemies are made, and a dangerous beast is unleashed upon the castle that only he can stop! First twenty chapters are just OC and then it merges into book 1
