After five exhilarating years in New York, Stevie has a successful career and glamorous social life. But what she most wants is a baby – an aspiration that feels impossible given that she is single, 38 and living in a tiny apartment in Manhattan, far away from most of her family in England. Determined to become a mother, Stevie returns to London and has a baby on her own. When she gives birth to Ash, she finds motherhood painfully at odds with her former life and her expectations. She begins to wonder if having a child was a mistake, and what she might be willing to do to escape. As she struggles with what her future might hold, revelations from the past change everything she believed about family and love.
