Hogwarts and the Deathly Ones

Hogwarts was abandoned after the war. Considered little more than a reminder of past greatness and great pain, it sat for 30 years unattended. When a mysterious message blazes its way across Europe, will hope be restored? Can a ball save the school? More than that, can it save people? Amidst festivities, a broken family, a displaced youth, and an undead girl all seek to heal.
