Symbiont

In a world irrevocably altered by SymboGen-designed parasites—once hailed as humanity's salvation from disease—Mira Grant's "Symbiont" plunges readers into a harrowing struggle for survival. These bio-engineered implants, intended to enhance life, have catastrophically turned on their hosts, transforming the majority of the global population into mindless, ravenous creatures. Amidst the spreading panic and forced quarantines of those seemingly unaffected, the story centers on Sal, a resilient protagonist grappling with the profound horror of this new reality. As society teeters on the brink of collapse, Sal and her desperate companions must uncover the insidious mechanisms by which these parasites seize control, decipher their ultimate, terrifying objective, and most critically, discover a way to halt their relentless advance before humanity is utterly consumed. It's a gripping tale of biological terror, societal breakdown, and the relentless fight for existence against an enemy that is intimately, horrifyingly, inside us all.
