William Twining is the orphaned son of the Twining family, one of Britain's oldest and most noble lines. When he learns his tuition has yet to be paid, he returns home to find the family...
It's family visiting day at the academy, but with his parents long dead and Kevin treating him like a stranger, William is feeling down. His mood quickly changes when the father of fellow prefect Swallow invites him to dinner, and the boy himself insists he wants William to "meet my parents."
A brilliant, skeptical noble accidentally summons a powerful demon and is forced to choose Hell's next ruler, while demons and angels battle for his nomination.
