In the middle of the nineteenth century, modern life is being born: the mind-boggling marvels of photography, the telegraph, and railroads; a flood of show business spectacles and newspapers; rampant sex and drugs and drink (and moral crusades against all three); Wall Street awash with money; and giddy utopian visions everywhere. Then, during a single amazing month at the beginning of 1848, history lurches: America wins its war of manifest destiny against Mexico, gold is discovered in northern California, and revolutions sweep across Europe–sending one eager English gentleman off on an epic transatlantic adventure. Amid the tumult, aristocratic Benjamin Knowles impulsively abandons the Old World to reinvent himself in New York, where he finds himself embraced by three restless young Americans: Timothy Skaggs, muckraking journalist, daguerreotypist, pleasure-seeker, stargazer; the fireman Duff Lucking, a sweet but dangerously damaged veteran of the Mexican War; and Duff’s dazzling sister Polly Lucking, a strong-minded, free thinking actress (and discreet part-time prostitute) with whom Ben falls hopelessly in love.
