During a party at the family farm in the English countryside, sixteen-year-old Laurel Nicolson has escaped to her childhood tree house and is dreaming of the future. She spies a stranger coming up the road and sees her mother speak to him. Before the afternoon is over, Laurel will witness a shocking crime that challenges everything she knows about her family and especially her mother, Dorothy. Now, fifty years later, Laurel is a successful and well-regarded actress, living in London. She returns to the family farm for Dorothy's ninetieth birthday and finds herself overwhelmed by questions she has not thought about for decades. From pre-WWII England through the Blitz, to the fifties and beyond, discover the secret history of three strangers from vastly different worlds-- Dorothy, Vivien, and Jimmy-- who meet by chance in wartime London and whose lives are forever entwined.
