Today, Good Morning America hosted Elizabeth Gilbert, whose Eat, Pray, Love: One Woman's Search for Everything Across Italy, India and Indonesia (Penguin mti, 978-0143118428, $16; Penguin Audio unabridged CD, $39.95) opens as a feature film tomorrow. From PW’s starred review: “Gilbert fully engages readers in the year's cultural and emotional tapestry--conveying rapture with infectious brio, recalling anguish with touching candor--as she details her exotic tableau with history, anecdote and impression.”

Authors on today’s Leonard Lopate Show:

Think-tanker David Callahan, whose Fortunes of Change: The Rise of the Liberal Rich and the Remaking of America (Wiley, 978-0470177112, $25.95) is just out this week.

American studies professor Edward P. Kohn recalled Hot Time in the Old Town: The Great Heat Wave of 1896 and the Making of Theodore Roosevelt (Basic Books, 978-0465013364, $27.95). PW wrote “He succeeds in bringing this little-known tragedy to light, but it is weakened rather than strengthened by the addition of an election narrative.”

On The Bob Edwards Show, medical journalist David Stipp served up The Youth Pill: Scientists at the Brink of an Anti-Aging Revolution (Current, 978-1617230004, $26.95; Tantor Media unabridged CD, $34.99). PW declared “Stipp’s lucid and spry exposition of the science is tantalizing enough on its own.”

Tonight on Tavis Smiley: anti-racist activist Tim Wise, author of Colorblind: The Rise of Post-Racial Politics and the Retreat from Racial Equity (City Lights, 978-0872865082, $14.95).

Due to the nature of live programming, scheduling is subject to change.
