(CNN) – South Carolina First Lady Jenny Sanford's memoir, "Staying True," has been fast-tracked and will now hit bookstores on February 5 instead of the original April release date.
Sanford's publisher, Ballantine Books, announced the new date on Tuesday.
Sanford landed the book deal in September, just a few months after her husband, South Carolina Gov. Mark Sanford, admitted to an affair with an Argentine woman. In December, Sanford released a statement saying she is filing for divorce "after many unsuccessful efforts at reconciliation."
According to a synopsis of the book on the publisher's Web site, her memoir "reveals the private ordeal behind her very public betrayal - and offers inspiration for anyone struggling to keep faith during life's most trying times."
"She chose to let Mark Sanford deal with the embarrassment and political fallout from his own actions while focusing her own efforts privately on raising their children to be men of character, even in the face of the lies their father has told," the synopsis reads.
