The Monk of Mokha - Dave Eggers

Mokhtar Alkhanshali is twenty-four and working as a doorman when he becomes fascinated with the rich history of coffee and Yemen's central place in it. He leaves San Francisco and travels deep into his ancestral home to tour terraced farms high in the country's rugged mountains. He collects samples and organizes farmers and is on the verge of success when civil war engulfs the country. Saudi bombs rain down, the U.S. embassy closes, and Mokhtar has to find a way out of Yemen with only his hopes on his back.
