Can love and honor conquer all? Mark Helprin's enchanting and sweeping novel springs from this deceptively simple question, and from the sight of a beautiful young woman, dressed in white, on the Staten Island Ferry, at the beginning of summer, 1946. Postwar New York glows with energy. Harry Copeland, an elite paratrooper who fought behind enemy lines in Europe, has returned home to run the family business. Yet his life is upended by a single encounter with the young singer and heiress Catherine Thomas Hale, as they each fall for the other in an instant. Harry and Catherine pursue one another in a romance played out in Broadway theaters, Long Island mansions, the offices of financiers, and the haunts of gangsters. Catherine's choice of Harry over her longtime fiancé endangers Harry's livelihood and eventually threatens his life. In the end, it is Harry's extraordinary wartime experience that gives him the character and means to fight for Catherine, and risk everything. Not since Winter's Tale has Mark Helprin written such a magically inspiring saga. Entrancing in its lyricism, In Sunlight and in Shadow so powerfully draws you into New York at the dawn of the modern age that, as in a vivid dream, you will not want to leave.
