Yesterday, Special Agent Pendergast still mourned the loss of his beloved wife, Helen, who died in a tragic accident in Africa twelve years ago. Today, he discovers she was murdered. Tomorrow, he will learn her most guarded secrets, leaving him to wonder: Who was the woman I married? Why was she murdered? And, above all . . . Who murdered her? FEVER DREAM Revenge is not sweet: It is essential.

Devastated by the discovery that his wife, Helen, was murdered, Special Agent Pendergast must have retribution. But revenge is not simple. As he stalks his wife's betrayers—a chase that takes him from the wild moors of Scotland to the bustling streets of New York City and the darkest bayous of Louisiana—he is also forced to dig further into Helen's past. And he is stunned to learn that Helen may have been a collaborator in her own murder. Peeling back the layers of deception, Pendergast realizes that the conspiracy is deeper, goes back generations, and is more monstrous than he could have ever imagined—and everything he's believed, everything he's trusted, everything he's understood . . . may be a horrific lie.

After his wife, Helen, is brazenly abducted before his eyes, Special Agent Pendergast furiously pursues the kidnappers, chasing them across the country and into Mexico. But then, things go terribly, tragically wrong; the kidnappers escape; and a shattered Pendergast retreats to his New York apartment and shuts out the world. But when a string of bizarre murders erupts across several Manhattan hotels-perpetrated by a boy who seems to have an almost psychic ability to elude capture-NYPD Lieutenant D'Agosta asks his friend Pendergast for help. Reluctant at first, Pendergast soon discovers that the killings are a message from his wife's kidnappers. But why a message? And what does it mean? When the kidnappers strike again at those closest to Pendergast, the FBI agent, filled anew with vengeful fury, sets out to track down and destroy those responsible. His journey takes him deep into the trackless forests of South America, where he ultimately finds himself face to face with an old evil that-rather than having been eradicated-is stirring anew... and with potentially world-altering consequences. Confucius once "Before you embark on a journey of revenge, first dig two graves." Pendergast is about to learn the hard way just how true those words still ring.
