Bird in Hand : Alison and Charlie, Claire and Ben seem like two picture-perfect couples. Alison and Charlie have a beautiful family and a home in the suburbs, while Claire and Ben's marriage revolves around their careers and city-based lives. Despite their differences, the two couples have remained close friends for ten years. But one terrifying moment in the dead of a New Jersey night will quickly - and unexpectedly - expose the fractures and stresses that lie beneath the surface. Alison and Claire, best friends since childhood, are now worlds apart. And as each of them tries to find a way forward, all four will be forced to examine the choices they have made and the lives they have built, and ultimately to ask themselves: What is happiness? Does true human nature lie in our wanting or in how deeply we allow our desires to consume us? Four people, two marriages, one lifelong friendship: Everything is about to change.
