Thanatos, the dead Horseman of the Apocalypse, has endured thousands of years of celibacy to prevent the end of days. But just one night with the wickedly sexy Aegis Guardian, Regan Cooper, shatters centuries of resolve. Yet their passion comes with a price. And Thanatos must face a truth more terrifying than an apocalypse - he's about to become a father. Demon-slayer Regan Cooper never imagined herself the maternal type, but with the fate of the world hanging in the balance she had no choice but to seduce Thanatos and bear his child. Now, as the final battle draws closer and his rage at being betrayed is overshadowed by an undeniable passion for the mother of his child, Thanatos has a life-shattering realization - to save the world, he must sacrifice the only thing he's ever wanted - a family.
