The author of Park Avenue Summer throws back the curtain on one of the most remarkable feuds in history: Alva Vanderbilt and Mrs. Astor's notorious battle for control of New York society during the Gilded Age.

1876. In the glittering world of Manhattan's upper crust, a woman’s value comes from her pedigree, dowry, and most importantly, her connections. They have few rights and even less independence—what they do have, is society, and society is paramount. The more celebrated the hostess, the more powerful the woman. And none is more powerful than Caroline Astor—the Mrs. Astor.

But times are changing.

Alva Vanderbilt has recently married into one of America's richest families. But what good is dizzying wealth when society refuses to acknowledge you? Alva, who knows what it is to have nothing, will do whatever it takes to have everything.

Sweeping three decades and based on true events, this is the mesmerizing story of two fascinating, complicated women going head to head, behaving badly, and discovering what’s truly at stake.
