📝 Description: Symbiont

Mira Grant’s Symbiont presents a science fiction narrative centered on biological horror. The story follows Sal and her companions as they investigate a global crisis triggered by medical implants. These tapeworms were originally engineered by SymboGen to cure diseases, but they have begun attacking their hosts. This malfunction has turned the majority of the world’s population into a ravenous horde. The plot focuses on the immediate aftermath of this outbreak. Authorities are gathering those who do not appear infected for quarantine purposes as panic spreads through society. Sal must work with her group to uncover the mechanism behind the tapeworms’ control over their hosts. They need to determine the parasites' ultimate goal and find a way to stop them before the situation worsens. This novel appeals to readers who enjoy speculative fiction that blends medical thriller elements with zombie apocalypse tropes. It suits audiences interested in near-future scenarios where scientific solutions go wrong. The book is less suitable for those seeking traditional fantasy or historical settings. Grant’s background in political and social commentary informs the narrative’s tension. The story remains grounded in the immediate survival of its characters against a biological threat.
