Genetically engineered tapeworms have nearly eradicated human illness, and most people carry one. Now the parasites are restless and want lives of their own.
From New York Times bestselling author Mira Grant comes a vision of a decade in the future, where humanity thrives in the absence of sickness and disease.
We owe our good health to a humble parasite — a genetically engineered tapeworm developed by the pioneering SymboGen Corporation. When implanted, the Intestinal Bodyguard worm protects us from illness, boosts our immune system — even secretes designer drugs. It's been successful beyond the scientists' wildest dreams. Now, years on, almost every human being has a SymboGen tapeworm living within them.
But these parasites are getting restless. They want their own lives . . . and will do anything to get them.
"A riveting near-future medical thriller that reads like the genetically-engineered love child of Robin Cook and Michael Crichton." —John Joseph Adams
