When her father dies suddenly, she's orphaned in her mid-twenties, her mother already long gone. Then Sue meets Annie. It's been twenty years, but Annie could never forget that face. She was Sue's live-in nanny at their big house upstate, and she loved Sue like she was her own. Craving connection and mothering, Sue is only too eager to welcome Annie back into her life; but as they become inseparable once again, Sue starts to uncover the truth about Annie's unsettling time in the Keller house all those years ago, particularly the manner of her departure - or dismissal. At the same time, she begins to grow increasingly alarmed for the safety of the two new charges currently in Annie's care. Told in alternating points of views - Annie in the mid-'90s and Sue in the present day - this taut novel of suspense will keep readers turning the pages right up to the shocking end.
