Two years after nearly losing her life in the Boston Marathon bombing, Annie David is still far from "Boston Strong." Instead she remains isolated and defeated--plagued by guilt over her niece who was crippled in the blast, and haunted by an antique ring alongside a hazy hero's face. But when she learns the identity of her rescuer, will he be the hero she imagined? And can the long-past history of the woman behind the ring free Annie from the guilt and fears of the present? Two women, separated by centuries, learn what true strength is.
