Query: Well Written and Thought Provoking

Life of Pi is a well written and thought provoking account of a young boy's survival story. Martel creates a vivid world, enhanced by his writing tone, which completely absorbs the reader. Through much of the story, though the events are tragic and horrific, we as readers get a feeling of hope and optimism- possibly because we know from the beginning that Pi lives to tell his story.This book is chock-full of literary themes and symbolism, and while it's a relatively short book with a narrow story, it absorbs the mind and heart. Bring with you a thick skin- the story is not a delightful romp with a boy and a tiger, and does take several disturbing, even haunting, turns. Overall though, Martel has given us a book with a fascinating story and has also raised many questions about the nature of humans, animals, and religion.
