Robert Louis Balfour Stevenson was a Scottish novelist, poet, and travel writer, and a leading representative of English literature. He was greatly admired by many authors, including Jorge Luis Borges, Ernest Hemingway, Rudyard Kipling and Vladimir Nabokov.
Most modernist writers dismissed him, however, because he was popular and did not write within their narrow definition of literature. It is only recently that critics have begun to look beyond Stevenson's popularity and allow him a place in the Western canon.
Upon second read and myself being much older, in my thirties, than when I first read it, in my twenties, I caught some details that I hadn't noticed before. Such as Jim Hawkins drinking brandy with the men and already knowing how to shoot a pistol and rifle. But, I had to think how back in the early 1700s and late 1800s when the story was written, life was a lot different and kids had to grow up a lot faster than they do now. I also noticed that the story was told from an older Jim Hawkins and he's reflecting on his past adventure, so he's able to add some clarification to the story that he didn't have at the time of of the "present" action of the story.
Knowing the story, I was looking forward to Billy Bones at the Admiral Benbow Inn, Jim in the apple barrel, and finally when we get to the "treasure island" meeting Ben Gunn.
The writing is simple and easy to follow, sucking the reader right in with Jim's adventures.
