In tightly controlled Terris, your future is rooted in the symbiotic fungi you bond with-organisms that grant abilities to serve society's needs. But Sora questions the overbearing Committee and longs for more than her isolated community offers.
When she and her friends break the rules and venture deep into the forest, they stumble upon a terrifying new fungus. A sudden burst of spores sends them scattering, and someone among them bonds with the deadly shroom, unleashing fear and a monstrous new threat.
In the chaos, Sora accidentally bonds with another unknown mushroom, giving her strange abilities of her own. Now, she may be the only one who can stop the horror descending on her home.
As the Death Shrooms twist bodies and minds, Sora must face a bone-chilling question: can she embrace her unexpected power to stop the nightmare engulfing Terris, or will her unique bond make her the next target?
