Life of Pi by Yann Martel
Piscine Molitor Patel decides his name will be Pi once his classmates begin to pronounce his name as pissing. He is not quiet so decisive when it comes to choosing a religion. He is a practicing Hindu, Christian and Muslim by the age of 16. He's a very likable boy.
His father owns a zoo. But politics cause him to uproot his family to take them to America. On the way the ship sinks. Pi had gone investigating in the middle of the night and wound up in a lifeboat by himself for a while. But it's not long before he is joined by a few fleeing animals. But very shortly the tiger has made meals out of the others. Now Pi must fight for survival not only against the ocean, but also against the tiger.
Life of Pi is a delightful book. Pi uses his fathers teaching along with his religious views to make sense of his situation. He sees God in everything and it helps keep his spirit up while he waits for rescue.
