A fantasy masterpiece from a five-time Hugo Award winner!A war-dragon of Babel crashes in the idyllic fields of a post-industrialized Faerie and, dragging himself into the nearest village, declares himself king and makes young Will his lieutenant.

Evacuated to the Tower of Babel -- infinitely high, infinitely vulgar, very much like New York City -- Will meets the confidence trickster Nat Whilk. Inside the Dread Tower, Will becomes a hero to the homeless living in the tunnels under the city, rises as an underling to a politician, and meets his one true love - a high-elven woman he dare not aspire to.You've heard of hard SF: This is hard fantasy from a master of the form.
