Robert Louis Stevenson's Treasure Island

Treasure Island is an adventure novel by Robert Louis Stevenson, narrating a tale of "pirates and buried gold". First published as a book in 1883, it was originally serialized in the children's magazine Young Folks between 1881-82 under the title The Sea Cook, or Treasure Island.
Traditionally considered a coming-of-age story, it is an adventure tale known for its atmosphere, character and action, and also a wry commentary on the ambiguity of morality-as seen in Long John Silver-unusual for children's literature then and now. It is one of the most frequently dramatized of all novels. The influence of Treasure Island on popular perception of pirates is vast, including treasure maps with an "X", schooners, the Black Spot, tropical islands, and one-legged seamen with parrots on their shoulders.
