From New York Times bestselling author Mira Grant comes the second book in the terrifying Parasitology series.
The SymboGen-designed tapeworms were created to relieve humanity of disease and sickness. But the implants in the majority of the world’s population began attacking their hosts, turning them into a ravenous horde.
Now those who do not appear to be afflicted are being gathered for quarantine as panic spreads, but Sal and her companions must discover how the tapeworms are taking over their hosts, what their eventual goal is, and how they can be stopped.
“A riveting near-future medical thriller that reads like the genetically-engineered love child of Robin Cook and Michael Crichton.” —John Joseph Adams on Parasite
