Across America a mysterious disease is turning ordinary people into raving, paranoid murderers who inflict brutal horrors on strangers, themselves, and even their own families. Working under the government’s shroud of secrecy, CIA operative Dew Phillips crisscrosses the country trying in vain to capture a live victim. With only decomposing corpses for clues, CDC epidemiologist Margaret Montoya races to analyze the science behind this deadly contagion. She discovers that these killers all have one thing in common – they’ve been contaminated by a bioengineered parasite, shaped by a complexity far beyond the limits of known science. Meanwhile Perry Dawsey – a hulking former football star now resigned to life as a cubicle-bound desk jockey – awakens one morning to find several mysterious welts growing on his body. Soon Perry finds himself acting and thinking strangely, hearing voices . . . he is infected. The fate of the human race may well depend on the bloody war Perry must wage with his own body, because the parasites want something from him, something that goes beyond mere murder.

From the acclaimed author of Infected comes an epic and exhilarating story of humanity’s secret battle against a horrific enemy. Across America, a mysterious pathogen transforms ordinary people into raging killers, psychopaths driven by a terrifying, alien agenda. The human race fights back, yet after every battle the disease responds, adapts, using sophisticated strategies and brilliant ruses to fool its pursuers. The only possible the epidemic is driven not by evolution but by some malevolent intelligence. Standing against this unimaginable threat is a small group, assembled under the strictest secrecy. Their best weapon is hulking former football star Perry Dawsey, left psychologically shattered by his own struggles with this terrible enemy, who possesses an unexplainable ability to locate the disease’s hosts. Violent and unpredictable, Perry is both the nation’s best hope and a terrifying liability. Hardened CIA veteran Dew Phillips must somehow forge a connection with him if they’re going to stand a chance against this maddeningly adaptable opponent. Alongside them is Margaret Montoya, a brilliant epidemiologist who fights for a cure even as she reels under the weight of endless horrors. These three and their team have kept humanity in the game, but that’s not good enough anymore, not when the disease turns contagious, triggering a fast countdown to Armageddon. Meanwhile, other enemies join the battle, and a new threat—one that comes from a most unexpected source—may ultimately prove the most dangerous of all. Catapulting the reader into a world where humanity’s life span is measured in hours and the president’s finger hovers over the nuclear button, rising star Scott Sigler takes us on a breathtaking, hyper-adrenalized ride filled with terror and jaw-dropping action. Contagious is a truly grand work of suspense, science, and horror from a new master.

The explosive conclusion to the New York Times bestselling trilogy that began with Infected and Contagious. The alien intelligence that unleashed two horrific assaults on humanity has been destroyed. But before it was brought down in flames, it launched one last payload-a tiny soda-can-sized canister filled with germs engineered to wreak new forms of havoc on the human race. That harmless-looking canister has languished under thousands of feet of water for years, undisturbed and impotent...until now. Days after the new disease is unleashed, a quarter of the human race is infected. Entire countries have fallen. And our planet's fate now rests on a small group of unlikely heroes, racing to find a cure before the enemies surrounding them can close in.
