The Dharma Bums - Jack Kerouac
Looooveeed this one by Mr. K. , has early dabble into Buddhism, traveling between 'nature' in his hikes and lonely retreats, and the city life so craved by the Beats. His character (which is him, right?), is at once a fire lookout on Desolation peak, and the next moment practicing Yab-Yum. (you'll have to read to find out...) Great copy in good shape.
