Emily has, by all appearances, a perfect life: a townhouse on Manhattan's Upper East Side, two healthy children, and a husband who showers her with attention. But the truth is more complicated: Emily's marriage is in trouble, her relationship with her parents is fraught, and she is still nursing a heartbreak from long ago. When Emily runs into her high school girlfriend at a cocktail party, that heartbreak comes roaring back. But Gen Hall is no longer the lanky, hungry kid with holes in her shoes who Emily loved in her youth. Instead, Gen is now a famous Olympic athlete with sponsorship deals and a string of high-profile ex-girlfriends.

Emily and Gen circle one another cautiously, drawn together by a magnetic attraction and scarred by their shared history. Once upon a time, Gen knew everything about Emily. And yet, she still abandoned her. Can Emily trust Gen again? Can they forgive each other for the mistakes they made in their past? Should Emily risk her children, her privacy, and the fragile peace she has found to be with a woman she loved long ago?
