Book excerpt: The new novel by the celebrated author of The Sunday Wife chronicles the lives of a tight-knit group of lifelong friends. None of the Same Sweet Girls are really girls anymore, and none of them have actually ever been that sweet. But this spirited group of Southern women, who have been holding biannual reunions ever since they were together in college, are nothing short of compelling. There's Julia Stovall, the First Lady of Alabama, who, despite her public veneer, is a down-to-earth gal who only wants to know who her husband is sneaking out with late at night. There's Lanier Sanders, whose husband won custody of their children after he found out about her fling with a colleague. Then there's Astor Deveaux, a former Broadway showgirl who simply can't keep her flirtations in check. And Corinne Cooper, whose incredible story comes to light as the novel unfolds.
