At times, novelist Robert Stone's trek through the '60s was literally a joy ride: He traveled cross-country with Ken Kesey's acid-fueled Merry Pranksters, imbibing psychedelics and the master's wisdom. Sometimes though, this Brooklyn-born Navy veteran was caught up in a different kind of history: He served as a correspondent in Vietnam and witnessed the Cold War invasion of Laos. Along the way, he metamorphosed into a major American writer: His 1967 novel, A Hall of Mirrors, won a William Faulkner Foundation prize, and his 1974 novel, Dog Soldiers, based partially on his Asian experiences, won a National Book Award. Prime Green recounts Stone's long, strange trip to greatness.
