When Charlotte regains consciousness after an accident, she finds herself living a stranger’s life. The previous five years are a blank, and her husband, Henri, and daughter, Ada, are strangers. Arriving at their family chateau in southern France, she hopes to regain her memories. Instead she feels isolated and unsettled. Strange events hint at underlying darkness and menace. Charlotte doesn’t know who to trust.
Did she really have an affair with their charming Irish neighbour, as her enigmatic mother-in-law suggests? And what of Henri? He seems loving and kind, a good parent, but Charlotte is wary. Then there is Ada, a little girl who just wants her mother back.
With the help of her friend and fellow Australian Susannah, Charlotte starts to piece together events, but her newfound confidence is shaken with news that puts a deadline on her quest.
