Authors on today’s Leonard Lopate Show:

Journalist Stephanie Syman described The Subtle Body: The Story of Yoga in America (FS&G, 978-0374236762, $28). PW’s review had this to say: “When she pulls back to view the culture mashup yoga has become—a cure for back pain, a beauty regime, and a route to God—she gives a cogent, engrossing analysis of this Asian-born spiritual practice turned all-American panacea.”

John Brandon, with his novel Citrus County (McSweeney's, 978-1934781531, $22), which PW considered “funny and horrifying. Brandon's dry wit, dark imagination, and surprisingly big heart combine to reveal a Florida that, despite (or because of) being more Ted Bundy than Disney World, is absolutely worth visiting.”

This weekend, Book TV's After Words interviews Michael Belfiore, author of The Department of Mad Scientists: How DARPA Is Remaking Our World, from the Internet to Artificial Limbs (Smithsonian, 978-0061577932, $26.99).
