Gulliver's Travels by Jonathan Swift
This masterpiece tells the incredible tale of Lemuel Gulliver, an English ship's surgeon. He is shipwrecked upon the shores of Lilliput, where the residents are only six inches high, then journeys takes him to the land of Brobdingnag, populated by giants, a floating island in the sky, and a land where horses have intelligence and man lives as a beast. His adventures, while read by children as an adventure story, are a devastating satire of society and human foibles. Part travelogue, part realism, part symbolism, Gullivers Travels remains a treasured classic of literature.
