Since 2000, America's most ambitious young evangelicals have been making their way to Patrick Henry College in Virginia, a small Christian school just outside the nation's capital. Most of them are homeschoolers whose idealism and discipline put the average American teenager to shame. In turn, "God's Harvard" grooms its students to be the Christian elite of tomorrow, dispatching them to the front lines of politics, entertainment, and science, to wage the battle to take back a godless nation.Hanna Rosin spent a year and a half at the college, following the students from campus to the White House and Congress, conservative think tanks, Hollywood, and other centers of influence. Her account captures a nerve center of the evangelical movement at a moment of maximum influence and also crisis, as it struggles to avoid the temptations of modern life and still remake the world in its own image.
