The story of two couples over three decades and a highly emotional hardcover novel about relationships for readers of "One Day." Two couples, three decades: In this novel by Katy Mahood, the paths of John and Stella repeatedly intersect with those of Charlie and Beth in the streets of London, where the pulse of the world beats. Although they do not know it and do not even know each other, these encounters will not be without consequences. As some plans succeed and others fail, as love transforms, fades, or returns even stronger, life continues to revolve around the four and their children. And the question remains: how we became who we are - and how even seemingly insignificant chance encounters can influence our lives.
