Leech

by Hiron Ennes

IntenseDarkSuspensefulMysteriousAtmosphericMoral ambiguitySecrets and liesIdentity crisisConspiracyPower dynamics

Leech plunges you into a perpetually frozen, isolated world where the Institute, a collective consciousness inhabiting human hosts, sends one of its doctors to investigate the death of a peer in a decaying provincial outpost. What begins as a medical inquiry quickly unravels into something far more unsettling. You'll experience the world through a deeply alien perspective, as the doctor navigates a web of strange family dynamics, environmental decay, and a creeping biological menace that blurs the lines between self and other. The book maintains a relentless, atmospheric dread, slowly revealing its secrets with a cold, precise intensity. It's a challenging, often disturbing read that will appeal to those who seek out gothic-tinged body horror, deeply weird fiction, and explorations of identity, power, and the terrifying unknown.
