Virtually every novelist in America fantasizes about being picked to appear on Oprah Winfrey's talk show. But now an increasing number of writers have discovered a new champion: Glenn Beck, the outspoken media darling of populist conservatism.

On his radio show and cable television programs, first on CNN Headline News and now on the Fox News Channel, Beck has enthusiastically endorsed dozens of novelists, a majority of them writing in the thriller genre. Beck, who now attracts 9 million weekly listeners on radio and 2.7 million daily viewers on television, often selects authors whose plots or characters reflect political stances that mirror his own. But he also promotes the work of authors who may disagree with many of his views.

"He's our Oprah," said Brad Thor, a writer of political thrillers who has appeared on Beck's radio and television programs several times. "God love him, we're very fortunate."

At a time when the book industry is struggling to maintain, much less increase, sales, publishers and authors say an appearance on Beck's television or radio programs helps attract new readers. After James Rollins, the author of "The Doomsday Key," a thriller about a group of Defense Department scientists trying to solve an ancient mystery, appeared this past summer on Beck's radio program and then his television show — on which Beck promised viewers "it will keep you on the edge of your seat" — Rollins met several people at a book signing who told him they had bought the book based on that recommendation, he said.

According to Seale Ballenger, a publicist for William Morrow, an imprint of HarperCollins that released "The Doomsday Key," the novel remained in the Top 10 of the New York Times hardcover fiction best-seller list longer than typical for its type. "It was totally driven by Glenn Beck," Ballenger said.

In the past five years Beck, who was a best-selling novelist with "A Christmas Sweater" last year, has interviewed about 40 thriller writers, including David Baldacci, Nelson DeMille and James Patterson, on his radio program, his cable television shows or both.

While his focus is thrillers, Beck stands out among talk show hosts in that he regularly interviews authors who write fiction at all. "I think it's an aspect of the show that maybe has flown under the radar because of some of the more controversial things that have taken place on the air," said Daniel Silva, an author of spy thrillers. Beck, Silva said, "has provided a really unique venue for novelists to come and talk about their work on television."
