The plot goes as so… Billy Bones, an old sea captain staying at the inn owned by young Jim Hawkins and his mother, is visited by some old friends and subsequently has a fatal seizure of some kind. Whilst collecting the rent from Bones’ chest Jim and his mother find a treasure map.
The local squire and doctor undertake to follow it to some place evidently in the Caribbean to find the treasure. In Bristol (where they go to buy a ship) they are manoeuvred into buying a particular one and staffing it with sailors recommended by the one-legged bar-keeper Long John Silver, who
also persuades Dr Livesey and the Squire to hire him as cook.
Whilst sailing, Jim overhears a conversation among Silver and many of the crew members and realizes that they are pirates, the same crew that buried the treasure that Jim and his friends are seeking. Once the ship reaches its destination, fighting soon breaks out between the pirates and Jim's friends. At one point the pirates have possession of the ship and replace the Union Jack with the Jolly Roger. At the end, of course, the non-pirates win and make their way to the treasure site marked on the map, only to discover that Ben Gunn, a sailor left behind by the original pirate crew, has already found and moved it. Since it's useless to him there, he's more or less willing to give up most of it in return for passage home. The party sets sail for home, with some of the pirates prisoners on board and others left behind on the island. On the way back home Long John Silver escapes with a bag of the treasure, though not the whole thing.
My personal opinion of this book is that it is very descriptive, allowing the reader to experience the world of Stevenson’s narrative and tag along with Jim as he embarks on the journey of a life time. I found that the author isn’t scared to put a twist in the plot, for example Jim chooses his crew then all a sudden a fight breaks out over the treasure. All in all, I believe teenagers would enjoy Treasure
Island, because it is an adventure story told in an exciting and accessible way.
