Overland on the Hippie Trail

It was a new age, one called the Age of Aquarius, with a restless, ideological generation full of a reverence for new worlds opening up to new ideas. When the Beatles introduced the mystique of India to pop culture, the Hippie Trail was established as hip adventurers traveled overland from Europe to Kathmandu and India.
Hunter was not among these hipsters. Still bitter over the way he was treated as a Marine combat veteran home from the Vietnam War, he felt the allure of the open road in America and in Europe. While getting visas in Vienna, he came across a Polish girl, Ewa, whose Politburo father got her unequal privileges she gladly abused to join Hunter on the trek to India to check out the new-age ashrams.
Shared experiences and hardships bonded them, but Cold War politics made falling in love the worst hardship of all.
