Sixteen-year-old Keanu has always navigated Willow Creek in a symphony of taupe and slate, his color blindness a shield against a vibrant world he couldn't comprehend. But when a parasitic entity known as "Thorne's Mirror" latches onto his psyche, Keanu's world is suddenly invaded by a "cacophony of color." This Polka-Dot Parasite doesn't just change his vision; it feeds on his anxiety, amplifying his deepest fears into vivid, inescapable hallucinations. Keanu must embark on an internal journey to the "very fabric of his own being" before the parasite's revenge becomes his reality.
