Inspired by a scientific study showing that hallucinogenic mushrooms can potentially cure obsessive-compulsive disorder, Adam Strauss embarked on his own program of vigilante psychopharmacology. As he uncovers an underground community of clandestine chemists, falls in love with a brilliant psychologist who takes him on as her unofficial research subject, and decamps to a remote island accompanied only by his geriatric pug dog and formidable pharmacopoeia, Adam’s relentless pursuit of his unorthodox cure is at once hilarious, harrowing, and heartrending.
