Tom Sawyer is among the best-known, most-loved characters in American fiction.

These adventures were based upon the author's real boyhood experiences along the Mississippi River. Trace Mark Twain's life from 1835, when his birth was heralded by Halley's Comet, to 1910, when the comet returned upon his death, in this fascinating biography by Newbery Honor author Sterling North.
