"Fast, fun, and wise--the perfect summer read."--Nancy Thayer, New York Times bestselling author of Family Reunion

At just thirty-five, reclusive billionaire Robbie Malcolm is a renowned financial prognosticator, a celebrated philanthropist, and a mathematical genius. Also, he's dying, which is a fact he's carefully concealing from the world.

As he takes stock, Robbie realizes that his wealth means nothing if he can't help the people who matter most. So he invites his oldest friends--Blair, Cat, and Wade--to their beloved Fenwick Island on the coast of Delaware to share his secret and to reveal plans for each of them that he believes will change their lives forever.

However, Robbie isn't the only one with secrets. The bonds the friends formed as teenagers still exist, but adulthood has brought a whole new set of complications, like unrequited loves, marriages on the brink, and so much unfulfilled potential. Robbie's plans may look good on paper, but are they any match for the utter disaster that is real life?

As everything comes to light over a wild weekend full of surprises, Robbie learns there are still some things money can't buy, and a group of friends who thought their best years were behind them realize just how much they have to look forward to.
