A string of blood-drained bodies appears in Chicago, then spreads across major American cities with impossible speed. Detective Marisol Vega and FBI profiler Dani Reyes uncover a pattern too organized, too precise, and too inhuman to explain away. Behind the killings stands an ancient hidden society of vampires divided between caution and conquest, as Cassius Vael tries to contain a war before Kael's ruthless escalation turns the world into a feeding ground. Red Tide is a dark supernatural thriller blending homicide investigation, federal manhunts, covert vampire politics, and a growing national nightmare.
