In a rare collaboration, bestselling authors Helprin and Van Allsburg worked for nearly a decade on this ambitious, multi-generational trilogy that pits the power of love and devotion against dark forces of greed and suppression. For the first time, this hardcover volume collects all three of Helprin's contemporary fantasies -- ''Swan Lake,'' ''The Veil of Snows,'' and ''A City in Winter'' -- along with Van Allsburg's sensitively wrought illustrations from the original editions. 42 full-color plates.
