What happens when the immortal finally have to pay? For nine hundred years, Casimir has fed without consequence. Then his closest companion dies after a single feeding-and human blood becomes a death sentence. An invisible strain kills most vampires outright. The rare survivors lose their immortality. Every human life they take ages them five years. The hunger remains, but forever is gone. Searching for answers, Casimir travels from Bucharest to Istanbul and Prague, where he meets Vesna, a changed vampire who has learned to ration her hunger and endure its cost. But their kind is turning against itself. Ancient vampires hunt the changed. Reckless survivors feed away their remaining years. And a forensic pathologist follows a trail of corpses that have aged decades in days. Caught between starvation and the terror of growing old, Casimir must decide what his remaining years are worth-and whose life he will take to survive. The Blood Age is an atmospheric vampire horror novella about hunger, mortality, and the price of centuries of killing. One life. Five years. Nothing taken without a cost.
