WSHU Public Radio's author talk "Join the Conversation" will host a talk by Nancy Gibbs, deputy managing editor of Time Magazine, Sunday, Sept. 16. It will be held 3 p.m. at Sacred Heart University's Edgerton Center for the Performing Arts, 5151 Park Ave.

Gibbs will discuss her book, "The Presidents Club: Inside the World's Most Exclusive Fraternity," co-authored by Time's executive editor Michael Duffy.

It draws upon newly revealed documents and hundreds of interviews to portray the complex emotions that have bound these men together and their unique office, according to a news release.

The work explores how each president came to realize the club's value; how each used it often for the good of the country and the office; and how it changed the course of history, from Truman to Obama, the release states.

Gibbs and Duffy are also authors of "The Preacher and the Presidents: Billy Graham in the White House."

Gibbs has written more than 150 Time cover stories, including an article for the special issue on 9/11 that won the National Magazine Award, and she was the lead Time writer for the last five presidential campaigns. She is a frequent guest on radio and television talk shows, including "Today," "Good Morning America," the "CBS Evening News," "Charlie Rose," and "NewsHour" on PBS.

She graduated from Yale University summa cum laude with honors in history, the release states.

Reservations are required and can be made at www.wshu.org. A $5 charge per person will be collected at the door. All paid attendees will receive a coupon for $5 off a copy of the author's book, usable on the night of the event only. Proceeds will help support WSHU Public Radio.
