CHICAGO — Elizabeth Edwards, wife of former presidential candidate and U.S. Sen. John Edwards, will promote her new book in Raleigh on May 16.

Set for a March 8 release, "Resilience" is the follow-up to her 2006 autobiography "Saving Graces," which focused on how she coped with the 1996 death of the couple's son and her ongoing battle with breast cancer.

"Resilience" serves as a sort of sequel, her publicist has said, talking in part about her husband's admission to an affair with a campaign worker in 2006 and about her recurrence of cancer.

Edwards will appear at Quail Ridge Books, 3522 Wade Ave., Raleigh at 3 p.m., Saturday, May 16 for a public signing. For more information, call 919-828-1588.

The event requires a ticket, which comes with a purchase of either of her books.

In an excerpt, Edwards writes that the news of her husband's affair made her vomit.

John Edwards went public with the affair in August after the National Enquirer reported he was the father of videographer Rielle Hunter's daughter.

He has denied paternity, but his wife of more than 30 years doesn't address the issue in her book.

She said her husband lied, saying he had sex with Hunter, whom she never mentions by name, once. The original confession "left most of the truth out," she writes.

Edwards is also set to appear on "The Oprah Winfrey Show" Thursday, in which she addresses the paternity speculation.

"That's what I understand," Edwards said in a video excerpt provided to The Associated Press. "I've seen a picture of the baby. I have no idea. It doesn't look like my children but I don't have any idea."
