Zen & the Art of Motorcycle Maintenance. Robert M. Pirsig. 2004.

Zen and the Art of Motorcycle Maintenance caused a sensation when it was first published in 1974. The story of the narrator, his son Chris and their month-long motorcycle odyssey from Minnesota to California profoundly affected an entire generation. Both personal and philosophical, this book is a compelling study of relationship, values, madness and eventually, enlightenment.
