The gravestone's inscription reads, "A man of courage. He made the greatest sacrifice of all." At the final resting place of Barney Davidson, in the hills of Bedfordshire, Ben Morgan first encounters Lucy and her grown daughter, Mary, on a snowswept afternoon in 1952. It is a meeting that will profoundly change all three -- a mother bowed but unbroken by stark tragedy, a young woman strangely untouched by the harshness of the world, and a loner seeking sanctuary in a simpler existence. But it is a shocking mystery from decades earlier that will truly bind them, heart and soul, as a long-hidden truth about the life and death of one extraordinary man slowly comes to light -- revealing the steps of a remarkable journey of strength, commitment . . . and undying love.
