Another TV personality behind a national bestseller is Good Morning America's Joan Lunden, whose Joan Lunden's Healthy Living (written with Laura Morton) takes the #8 spot on our nonfiction list. A fourth printing for the Crown title, which was published on April 9, brings the in-print total to 250,000. The first of Lunden's many national TV dates was -- surprise! -- on GMA; she's also appeared with Conan O'Brien, Oprah, Larry King and Rosie O'Donnell (will Rosie reciprocate with her book, we wonder?). Still to come are Fox After Breakfast and The Charlie Rose Show, plus a TV satellite tour set for April 16. A feature article (which outlines Lunden's busy book-signing schedule) appears in the April Good Housekeeping, and full-page ads are set for People and In Style magazines.
