In an unnamed Middle Eastern security state, a young Arab-Indian hacker shields his clients—dissidents, outlaws, Islamists, and other watched groups—from surveillance and tries to stay out of trouble. He goes by Alif—the first letter of the Arabic alphabet, and a convenient handle to hide behind. The aristocratic woman Alif loves has jilted him for a prince chosen by her parents, and his computer has just been breached by the state’s electronic security force, putting his clients and his own neck on the line. Then it turns out his lover’s new fiancé is the "Hand of God," as they call the head of state security, and his henchmen come after Alif, driving him underground.

High above Manhattan android and human steelworkers are constructing a new Tower of Babel for billionaire Harry Gant, as a monument to humanity’s power to dream. In the festering sewers below a darker game is afoot: a Wall Street takeover artist has been murdered, and Gant’s crusading ex-wife, Joan Fine, has been hired to find out why. The year is 2023, and Ayn Rand has been resurrected and bottled in a hurricane lamp to serve as Joan's assistant; an eco-terrorist named Philo Dufrense travels in a pink-and-green submarine designed by Howard Hughes; a Volkswagen Beetle is possessed by the spirit of Abbey Hoffman; Meisterbrau, a mutant great white shark, is running loose in the sewers beneath Times Square; and a one-armed 181-year-old Civil War veteran joins Joan and Ayn in their quest for the truth. All of whom, and many more besides, are caught up in a vast conspiracy involving Walt Disney, J. Edgar Hoover, and a mob of homicidal robots.
