What is the full summary of Robert Louis Stevenson's Treasure Island?

One day, an old sailor, Billy Bones, appears at the
Admiral Benbow Inn, where he decides to stay for a time. He becomes friendly with young
Jim Hawkins, the son of the inn's owner. It is clear that Bones is hiding from someone
at the out-of-the-way location, and he eventually meets up with some desperate looking
buccaneers. Bones' health deteriorates from his excessive rum drinking, and when he
dies, Jim finds a treasure map in Bones' trunk.

Sharing the
map with Dr. Livesey and the wealthy Squire Trelawney, the squire agrees to finance an
expedition to find the treasure. Before they leave the port in Bristol, they hire on an
experienced, one-legged sailor known as Long John Silver to be their cook during the
voyage. While on board, however, Jim overhears Silver discussing his decision to mutiny
and take over the ship--and find the treasure for
himself.

Silver and a large number of the crew eventually
mutiny, leaving the Squire, Livesey, Jim and the ship's captain with a small group of
loyal men. They are forced to abandon the ship, and they head ashore to defend
themselves from the mutineers. Meanwhile, Jim discovers a forlorn castaway, Ben Gunn,
who has been left on the island by the infamous pirate Captain Flint. Gunn tells Jim
that he knows the location of the buried treasure.

The
Squire and his men find an abandoned stockade on the island which they decide to defend.
They fight off several attacks by the pirates but are eventually forced to abandon the
little fort. Leaving his friends behind, Jim decides to try and make it back to the ship
in Gunn's little boat. Jim overwhelms the sole remaining mutineer and hides the ship in
a hidden lagoon.

When Jim returns to the stockade, instead
of finding the Squire and his men, he finds Silver and the pirates. Jim follows Silver
and the pirates to find the treasure, but when they reach the spot on the map, the
treasure is not there. Silver is forced to defend himself from the angry pirates, but
shots ring out from the Squire's hidden men. Silver joins the Squire, leaving his old
mates on their own. The Squire and his men retreat to the cave where Gunn has hidden the
treasure, and the men load the gold and silver aboard the ship. They eventually sail
away, taking Silver with them but leaving the other mutineers behind. Before the ship
reaches port, Silver steals away, never to be seen again. The others eventually return
to England, rich beyond their wildest dreams.
