Books in the Lords of Deliverance series

The prophesies were there . . . but no one listened. They are the four Horsemen of the Apocalypse and they have the power to usher in Doomsday . . . or prevent it.Eight months ago, demon-slayer Regan Matthews seduced the fourth Horseman of the Apocalypse, Thanatos. Now, she's pregnant with his child - a child who, if prophecies are to believed, is fated to save the world. But things aren't always as they appear, and the baby conceived by two warriors may yet be the very catalyst that kicks off Armageddon. Thanatos, who will be Death when his Seal breaks, never thought he'd have a family, but as he grows close to Regan and his unborn son, he allows himself to dream. But as the world edges closer to the end of days and his evil brother plots against him, Thanatos realises that the sacrifice he must make will destroy everything he dreamed of having.
