Zen and the Art of Motorcycle Maintenance

Here is the book that transformed a generation: an unforgettable narration of a summer motorcycle trip across America's Northwest, undertaken by a father and his young son. A story of love and fear--of growth, discovery, and acceptance--that becomes a profound personal and philosophical odyssey into life's fundamental questions, this uniquely exhilarating modern classic is both touching and transcendent, resonant with the myriad confusions of existence . . . and the small, essential triumphs that propel us forward.

Was banned for a period of time because it was "too controversial".

No one knows to this day what that means.
