Symbiont

Following Parasite, this is the second book in this CONTAGIOUS series about a miracle cure ... and a nightmare side-effect - from the New York Times bestselling author of Feed THE ENEMY IS INSIDE US. The SymboGen-designed parasites 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 parasites are taking over their hosts, what their eventual goal is and how they can be stopped.
