Holden Caulfield from Catcher in the Rye returns as Mark Stenrud to bring the psychedelic era vividly life in Lost and Found in the 60s. Alienated from a toxic mother, and in constant conflict at his conservative high school because of his radical politics, Mark Stenrud escapes for Haight-Ashbury, where he takes a job in the post office and settles into a carefree existence in the psychedelic center of the universe. LSD chemists notice his organizational skills and calmness in the face of danger and recruit him to join their enterprise. He accepts and has free time for romance, adventures, and street justice. After months of success, he loses his touch, leading to narrow escapes, bad decisions, and his own downfall. Along the way, he learns about loss, forgiveness, and the meaning of self-respect.
