Summary of Life of Pi
Pi Patel is an unusual boy, the son of a zookeeper in India. When Pi is sixteen, his family decides to emigrate to North America aboard a Japanese cargo ship, transporting their zoo animals to new homes. Tragedy strikes when the ship sinks. Pi finds himself alone on a lifeboat, accompanied only by a hyena, an orangutan, a wounded zebra, and Richard Parker, a 450-pound Bengal tiger. The tiger soon kills the other animals, leaving Pi and Richard Parker alone. Using his fear, knowledge, and cunning, Pi manages to coexist with the tiger for 227 days lost at sea. Eventually, they reach the coast of Mexico. Richard Parker escapes into the jungle and is never seen again. If you'd like, I can provide more details about the plot, themes, or characters!
