A dark and suspenseful novel of lies, betrayal, and identity - perfect for fans of Big Little Lies and Charlie Brooker's Black Mirror. It was meant to be an evening to honour and celebrate Evelyn Caldwell's award-winning, career-making scientific research - but Evelyn has things on her mind. Things like Nathan, her husband, who has left her for a younger, better, newer woman. A woman who is now pregnant - but shouldn't be - and is strikingly familiar. Too familiar to be a coincidence. A woman who shouldn't exist. The Echo Wife is a propulsive new novel from an international rising star about identity, murder, and the choices society forces women to make.
