Very easy to answer! Jules Verne's Mysterious Island. This is a sequel to 20,000 Leagues Under the Sea and is my all time favorite book. I must have read that 20 times so far. It has been made into a few movies and TV series but never close to the book. It is purely a survival story from the 1880's, written in the 1880's and good clean entertainment. I highly recommend this to anyone. CHeers!
