The action-packed adventure novel Treasure Island by Robert Louis Stevenson tells of the discovery of a treasure map followed by a sea voyage to a remote island holding hidden pirate treasure. The book is narrated by a boy named Jim Hawkins. In this gripping novel, Stevenson keeps the pace swift for readers of all ages by unfolding one exciting plot point after another. The author divides the book into six parts, and the easiest way to clarify the major events is to summarize the significant happenings in each part.
In part one, "The Old Buccaneer," Jim tells how an old sailor who calls himself the captain but whose real name is Billy Bones arrives at the Admiral Benbow, an inn owned by Jim's parents. Jim's father dies, and then Billy Bones dies. Jim and his mother go through Bones' sea chest for the money he owes them and Jim takes a sealed packet. Pirates who attack the inn are fought off. When Jim's packet is opened at Squire Trelawney's house, the treasure map of a pirate named Flint is found. Trelawney proposes a voyage to find the treasure with Dr. Livesey as ship's doctor and Jim as cabin boy.
In part two, "The Sea Cook," Trelawney has bought a boat called the Hispaniola and hired a crew with the help of a cook named Long John Silver. As they all board the ship, Captain Smollett tells Trelawney that he doesn't trust the crew that Silver has hired. Everyone knows about the treasure map, though Trelawney was supposed to keep it secret. On the voyage, Jim learns that most of the crew are pirates, including Silver. Jim tells Captain Smollett, Trelawney, and Livesey what he has found out.
In part three, "My Shore Adventure," Silver takes some men ashore and Jim comes along. When they reach land, Jim runs away. Jim observes Silver as he murders a pirate who refuses to cooperate. Later, Jim comes across a marooned, half-crazy Englishman named Ben Gunn, an original member of Flint's crew.
In part four, "The Stockade," Doctor Livesey takes over the narrative to tell how the loyal ship's company abandons the ship and takes up defensive positions in a stockade they find on the island. Jim takes up the narrative again to tell how he sees the British flag flying over the stockade and then rejoins the crew. The pirates approach for a parlay followed by an attack on the stockade, which is repulsed.
In part five, "My Sea Adventure," Jim sneaks out of the stockade and rows Ben Gunn's little boat out to the Hispaniola. Jim manages to set the ship adrift, take down the pirate flag, and safely beach the ship. A pirate named Hands wounds Jim with a knife, but Jim kills Hands with a pair of pistols. When Jim returns to the stockade, he is captured by the pirates that have taken it over.
In part six, "Captain Silver," Jim accompanies Silver and the pirates that are left...
as they search for the treasure. They find the treasure site but the treasure is not there. The loyal ship's crew surrounds the pirates, and Livesey says that Ben Gunn long ago found the treasure and moved it to another location. After transferring most of the treasure to their ship, the crew sails home, leaving three pirates marooned on the island. Silver escapes on the way. Jim, Trelawney, Livesey, Smollett, and others make it safely back to England and share the treasure.
