Wealthy Hermosa Beach housewife Nancy Hadley is no pushover. So when her philandering husband, Roger, is caught in flagrante with an opportunistic widow on their racing yacht, Nancy sticks it to him. She tells him she wants a divorce - with the yacht, Bucephalus, part of the deal, too.

Roger would rather make Nancy's life a living hell than give up his boat. But Nancy has other plans. After moving out of their opulent home, she and her posse of girlfriends invest in a racing yacht of their own to live on, and she teaches them the fine points of sailing. Meanwhile, and unbeknownst to Nancy, a big real-estate development is under way that would destroy her beloved harbor and new home.

When scheming Roger returns to ask Nancy to help capture the last committee vote - held by Nancy's old college friend - Nancy prepares for battle. Nancy is not skittish about taking a few risks, so in a bold gambit, she makes a bet with Roger: a showdown in the thrilling Border Dash Race from Newport Harbor down to Ensenada, Mexico. The winner of the race will get everything they want.

The stage is set for the race of a lifetime - and the tantalizing possibility of new romance for Nancy - in a novel as heartwarming as it is breathlessly exciting.
