For seventeen years, they waited in the dark. Now, the massive cicada emergence along Mercy Creek has brought a deafening roar to the woods-and awakened a parasitic predator that has terrifyingly adapted to the top of the food chain.
When their school bus overheats on an isolated, canopy-covered road, middle school science teacher Rachel and veteran driver Leon find themselves stranded with a handful of students in a sea of suffocating noise. The true nightmare begins when a student is snatched into the trees by giant, mutated wasps. These apex insects don't hunt by sight; they track the carbon dioxide of exhaled breath, delivering a paralyzing sting that leaves their victims fully conscious as they are dragged into the branches to serve as living incubators.
As the bus's flimsy defenses begin to buckle under the swarm, Rachel must abandon their only shelter. Teaming up with a desperate field entomologist, she leads her terrified students on a harrowing trek through the dark toward a concrete forestry depot. Forced to navigate a claustrophobic, inescapable environment where a single gasp can draw the swarm, the group faces a relentless, biologically grounded horror. Brood Country is a gripping, scientifically plausible survival thriller where humanity is stripped of its armor, and every exhale could be your last.
