The last true Mortals, called Sovereigns, hide in ruined cities while the emotionless Order and vicious Dark Bloods tighten their control. With their numbers dwindling and hope fading, Rom and his companions must choose between a desperate, violent gambit and a costly trust in the way of sacrificial love.

Nine years after Rom Sebastian first awakened emotion in a dead world, a boy named Jonathan—born with living blood in his veins—stands ready to take the throne. As Dark Blood armies rise and betrayal festers within, the fragile band of Mortals must decide what they’re willing to sacrifice for true life.

In a frozen Russian wasteland, two hermits are entrusted with a secret so terrible it could one day save or doom humanity. When a mysterious stranger arrives at their fire with a vial of potent blood and a dire warning, they must decide who can be trusted to guard the truth.

Centuries after a catastrophe stripped humanity of all emotions but fear, young Rom Sebastian receives a vial of ancient blood and a cryptic message. Drinking it awakens love, joy, and pain—and makes him a hunted man whose very heartbeat threatens the totalitarian Order that rules the world.
