Long a hub for literary bohemians, countercultural musicians, and readers interested in a good browse, Kepler's Books and Magazines is one of the most influential independent bookstores in American history. When owner Roy Kepler opened the San Francisco Bay Area store in 1955, he led the way as a pioneer in the "paperback revolution." He popularized the once radical idea of selling affordable books in an intellectually bracing coffeehouse atmosphere.

Paperback selling was not the only revolution Kepler supported, however. In Radical Chapters, Doyle sheds light on Kepler's remarkable contributions to pacifism and social change. He highlights Kepler's achievements in advocating radical pacifism during World War II, antinuclear activism during the Cold War era, and antiwar activism during the Vietnam War. During those decades, Kepler played an integral role, creating a community and a space to exchange ideas for such notable figures as Jerry Garcia, Joan Baez, and Stewart Brand. Doyle's fascinating chronicle captures the man who inspired that community and offers a moving tribute to his legacy.
In a new foreword for this revised edition, Doyle updates Kepler's story and assesses how the bookstore and the community it serves have remained socially engaged and commercially viable amid the tumult of the twenty-first century.
