Treasure Island follows young Jim Hawkins, who finds himself owner of a map to Treasure Island, where the fabled pirate booty is buried; honest Captain Smollett, heroic Dr. Livesey, and the good-hearted but obtuse Squire Trelawney, who help Jim on his quest for the treasure; the frightening Blind Pew, double-dealing Israel Hands, and seemingly mad Ben Gunn, buccaneers of varying shades of menace; and, of course, garrulous, affable, ambiguous Long John Silver, who is one moment a friendly, laughing, one-legged sea-cook . . .and the next a dangerous pirate leader. The unexpected and complex relationship that develops between Silver and Jim helps transform what seems at first to be a simple, rip-roaring adventure story into a deeply moving study of a boy’s growth into manhood, as he learns hard lessons about friendship, loyalty, courage and honor—and the uncertain meaning of good and evil.
