The Lazarus Culture(2009)
A novel by Pasquale J Morrone
Secret Service Agent Christopher Kearns had no idea what he was up against. Assigned on a temporary basis to the Center for Disease Control, he only knew that somehow it was connected to the lives of those the agency protected...namely, the President of the United States. If there were possible terrorist activities in the making, he could only guess it was at a red alert basis. When Kearns meets and befriends Doctor Marlene Peterson of the Breezy Point Medical Center in Maryland, he soon finds that science fiction can indeed become a reality. In a solitary room walked a man with no vital signs:dead. The explanation he received came from Doctor Lee Fret, a man assigned to the case from the CDC. Something was attached to the brain stem. Something alive that was quickly spreading rapidly through Maryland and other states. Kearns and his ragtag army of agents and medical personnel soon find themselves in a world of meaningless slaughter and mayhem. The armies of the walking dead were far more than mere zombies. Some began to change into whatever it was they ate. The government had found a way to reanimate the dead by implanting a parasite found on the tongue of the Red Snapper to the human brain. It looked good on paper, but it was a project straight from Hell. The dead now walked, but it wasn't a mystery. It was The Lazarus Culture.
