That same week, but many, many years before, a famously eccentric writer in Hartford, Connecticut, is putting the finishing touches on a manuscript about a rebellious boy named Huck. Suddenly, a bizarre thing happens: The manuscript disappears and in its place appears a strange contraption-a college student's laptop that has traveled through time.
