The Fungus
by Knight, Harry Adam
Harry Adam Knight does not waste time with subtlety in The Fungus. A scientific experiment involving a rapidly mutating fungus goes sideways, and London is quickly turned into a damp, spore-choked nightmare. This is quintessential 80s creature-feature horror, prioritizing visceral, skin-crawling physical transformations and a relentless pace. The atmosphere is thick with claustrophobia as the characters realize the very air they breathe has become the enemy. It is nasty, bleak, and intentionally grotesque, functioning as a high-octane survival story where nature does not just fight back, it consumes. Pick this up if you enjoy B-movie sensibilities, body horror that refuses to look away, and stories where the human race is significantly outmatched by a biological entity it never should have touched in the first place.
