New York, New York, it's a wonderful town! And Mark Helprin's new near-epic novel makes it all the more marvelous. It's got great polarized motifs — war and peace, heroism and cowardice, crime and civility, pleasure and business, love and hate, bias and acceptance — which the gifted novelist weaves into a grand, old-fashioned romance, a New York love story that begins with a Hollywoodish meet-cute on the Staten Island Ferry.
