Treasure Island.
Robinson Crusoe. Based on a true story. A sailor maned Alexander Selkirk was marooned on Juan Fernandez island. Actually, it was his choice rather than continue in what he thought was a cursed ship.

Kidnapped is also a favorite. (Robert Louis Stevenson)

These days I'm deeply into books by Bernard Cornwell. Today's favorite, 1356. All those battles between the French and the English, lots of blood and gore; I feel sorry for the horses.The English archers took them out to make the French men at arms fight on foot which they did not like to do.
I have to wonder if they were really that cruel in those days.
