    First published in 2001, the book Life of Pi written by Canadian author Yann Martel won the Man Booker Prize and an Asian American Prize for Literature. It is the story of a young boy named Pi who spends 227 days at sea with a small group of animals after disaster strikes their ship and is an account of his journey of survival and hardship.

    Piscine “Pi” Molitor Patel, on whom Life of Pi is based, is a young boy living in Pondicherry, India, where his father owns a zoo. The story starts when Patel's family decide to move to Canada, along with their zoo animals for their new home.

    However, because of the bad weather, the ship sinks. Pi along with an orangutan (猩猩), an injured zebra, a hyena (鬣狗) and a Bengal tiger named Richard Parker are the only survivors who take shelter in a small lifeboat. Both the injured zebra and the orangutan are soon killed and eaten by the hyena. The tiger in turn kills and eats the hyena, leaving just the two of them alone on the boat now.

    In an effort to avoid being eaten by Richard Parker, Pi acts himself as the head of the group and remains safe from harm. Since he does not want the tiger to die for fear of going mad by being alone on the boat, he fishes and feeds the two of them in order to stay alive.

    The life of Pi then enters its third stage when their lifeboat washes up on the shores of Mexico and the tiger escapes into a nearby forest leaving Pi alone. After the Mexicans refuse to believe Pi's story, he changes his tale by replacing the animals with his mother, a cook and a sailor and asks the Mexicans which one they prefer. They prefer hearing the first story though they do not believe a word of it.

    In my view, Life of Pi is a must read book for all those who love reading.
