"The Demons have declared war on Mike Travis and it ain't going to be pretty, see. You just offed one of their big boys and his bitch and they aint going to let that go easy down there." Dai Bricks. The Sin Eater. Things just got hotter and darker for Mike Travis after he killed the demon Astaroth in the cursed village of Aberth, Monmouthshire. Now they are out to get him, but not before they make him suffer. He must leave behind the paranormal investigations and become something else, something darker: become a demon hunter. Unwilling to sit back and wait for the fight, he takes it to them especially when those he loves are targeted by Malgron, a high-ranking demon and brother of Astaroth. His fight strengthens friendships and loyalties but, also brings with it surprising revelations and sacrifices. As the demons attack those closest to him, Mike must meet the darkness head-on, in a place where darkness itself is spawned and raised. Nothing will ever be the same again.
