As he leads her back to 1944 through his fascinating stories, Earle offers insight into his perilous journey over the Pyrenees, draws attention to the bravery of the men and women of the French Resistance, and highlights the heroism and friendships that existed among those missing in action, resistance fighters, locals, and within the Catholic Church. But it is not until tragedy strikes that the truth is finally revealed to Libby about her true identity. Many Shades of Blue is the extraordinary story of an American pilot's experiences during the Second World War as the past collides with the present and answers a young woman's questions about her birth.
