A freak combination of storm conditions and unusually good growing weather produces a catastrophe: Mama Lewis wakes up to find his house entirely surrounded by killer, man-eating choko vines with hostile intentions. Without access to conventional weapons, he discovers that the most effective countermeasure is unconventional in the extreme. What follows is an escalating battle against a sprawling eldritch horror that forces him down into a subterranean world he had no idea existed, full of rancid slime and aggressively threatening chokos. His gag reflex and his sanity are both going to be tested before this is over.
