The Odds: A Love Story, by Stewart O'Nan

Beautifully written yet ultimately unsatifying novel from one of my favorite writers, O'Nan.  Art and Marion have lost almost everything- their marriage is fractured from infidelities and they are on the verge of losing their home. In a last desperate weekend, they revisit Niagara Falls, the site of their honeymoon, and bet their last remaining assets on a roulette wheel.
