Elizabeth Edwards' publicist would not reveal whether Edwards would address the alleged daughter, Frances Quinn, in the memoir.
Edwards is suffering from bone cancer, which was diagnosed as incurable during her husband's 2008 presidential campaign.
"Resilience" is "an unsentimental and ultimately inspirational meditation on the gifts we can find among life’s biggest challenges," the Broadway Books catalog reads and is a follow-up to her memoir "Saving Graces."
