Step into Wilshire, home to some of the wealthiest people in the world, where the mansions are tastefully designed, the lawns are expertly manicured, and the streets are as hushed as the complexities in the residents' lives. While Wilshire's husbands battle each other in the financial world of nearby Manhattan, their wives manage their estates and raise the next elite generation. Some women are envied, some respected, and others simply tolerated. But regardless of where they stand, each woman is defined by the world she inhabits and would appear to do anything to keep it.

For Roslyn Barlow, the most socially admired woman in Wilshire, 'keeping it' means silencing the scandalous gossip threatening her daughter's reputation. For Caitlin Barlow, it means navigating life as a teenager in a culture of wealth and sexual promiscuity. For Sarah Livingston, it means quelling the terror she feels at having another child that will bind her more closely to a world she's grown to resent. And for Jacqueline Halstead, who's just discovered her husband is under investigation for embezzlement, keeping the life he's put at risk means doing the unthinkable - and her actions could shake Wilshire to its core.
