Trinity's Nine — C.R. Kwiat

Rachael Forester was told that her father was a violent man, but when a stranger shows up at Rachael's school, the terrible truth comes to light. Her father, Lord Trinity, is in jail; but the twisted power he has over a secret cult remains firm. Bounty hunters have been unleashed to capture Rachael, the ninth of ten sacrifices promised to Trinity's God of Power in exchange for monetary fortune.

Only a small group stands in the way, and they have already failed twice.
