Four college roommates awaken to a terrifying truth: they have been reborn five hours before the zombie apocalypse. This time, they refuse to die. While the world collapses outside their dorm, they gather supplies, protect their pregnant friend Emily, and fight to survive behind barricaded walls. Along the way, they meet unexpected allies, face hunger, fear, and ruthless survivors, and witness the birth of a fragile baby girl named Little Star. When the child survives infection, her blood may become humanity’s last hope. In the ruins of the old world, love, sacrifice, and new life begin again.
