The Immortals (The Immortals Series Book 1)

When demons refuse to play by the rules, all Hell will break loose.

Colin and Anna have been hunting demons for a long time. But something is different in Baton Rouge. The rules are being broken and they're powerless against some of the greatest forces Hell can assemble. If they can't stop these demons from manipulating every rule of this war, then Heaven may lose the only battle that's ever really mattered.
