Cansada de someterse a la voluntad de sus padres, Lexie Sinclair decide abandonar la casa familiar en el campo e instalarse en Londres. Allí conoce a Innes Kent, el editor de una revista de arte que la introducirá en los ambientes bohemios del Soho de mediados de los años cincuenta, y empezará una vida completamente distinta a la que estaba prevista para ella. Años más tarde, en el Londres actual, la maternidad ha trastocado la vida de Elina: un día se olvida de los zapatos al salir de casa y al otro es incapaz de recordar el día del parto. Mientras, Ted, el padre de su hijo, se va encerrando en sí mismo y empieza a recordar episodios de su infancia que había olvidado.
Lexie Sinclair is plotting an extraordinary life for herself. Hedged in by her parents' genteel country life, she plans her escape to London. There, she takes up with Innes Kent, a magazine editor who introduces her to the thrilling, underground world of bohemian, post-war Soho. She learns to be a reporter, to know art and artists, to embrace her life fully and with a deep love at the center of it. And when she finds herself pregnant, she doesn't hesitate to have the baby on her own. Later, in present-day London, a young painter named Elina dizzily navigates the first weeks of motherhood. She doesn't recognize herself: she finds herself walking outside with no shoes; she goes to the restaurant for lunch at nine in the morning; she can't recall the small matter of giving birth. But for her boyfriend, Ted, fatherhood is calling up lost memories, with images he cannot place. As Ted's memories become more disconcerting and more frequent, it seems that something might connect these two stories—these two women—something that becomes all the more heartbreaking and beautiful as they all hurtle toward its revelation.
