Russell and Corrine Calloway seem to be living the dream: a calendar filled with high-society parties; jobs they care about and enjoy; twin children, a boy and a girl whose birth was truly miraculous; a loft in TriBeCa and summers in the Hamptons. But beneath the glossy surfaces, things are simmering. Russell, editor-in-chief of a boutique publisher, has cultural clout but is on the edge financially, and feels compelled to pursue an audacious --- and potentially ruinous --- opportunity. Meanwhile, Corrine’s world is turned upside down when the man with whom she’d had an ill-fated affair in the wake of 9/11 suddenly reappears, and the Calloways find themselves tested more severely than they ever could have imagined.
