Alison and her groom, Luca, have just exchanged wedding vows and are preparing to cap off their perfect day at the reception. But before the champagne even hits the crystal stemware, Luca's first wife storms in and snatches back her children in front of the horrified guests. When the fuss has died down, Alison's friend Sarah confides that a few women she knows have started the Second Wives Club, where they get together to vent about the drama that inevitably unfolds when you share your husband with another woman.

The club's founding members include Julia, a stunning "May" wife whose "December" husband insists on remaining uncomfortably close to his former spouse; Susan, whose husband is the classic widower who can't let go of his ex's memory; and, of course, Sarah herself, whose cross to bear is a bitch on wheels, not unlike Alison's uninvited wedding guest. Together, they ride the roller-coaster of their chosen lives and—as they contend with malicious gossip, scheming divorce lawyers, and ex-wives intent on sabotaging their relationships—ultimately must decide what's best for their marriages, their husbands, and themselves.

Turning the tables on the usual sympathy for first wives, Jane Moore's dishy novel and lovable ensemble cast is a brilliant, unputdownable look at the modern marital love triangle.
