From the authors of the New York Times bestsellers The Strain and The Fall comes the final volume in one of the most electrifying thriller series in years. It’s been two years since the vampiric virus was unleashed in The Strain and the entire world now lies on the brink of annihilation. Humankind’s only hope for salvation is Dr. Ephraim Goodweather—head of the Centers for Disease Control’s team—and his ragtag band of freedom fighters. But who will pay the ultimate sacrifice—so that others may be saved?
