Just finished reading Life of Pi, by Yann Martel. Going into it, I didn't know a whole lot about the book -- just that it was about a boy and a tiger in a boat. It turned out to be a pretty amazing story of survival under bizarre circumstances. Apparently it is based on a true story, but fiction written mostly in the first person. I'll have to do a little more research to find if it really is a true story. Highly recommended, and can't say much more about it without ruining the story for you.

Update: After no more than 5 minutes doing a little Google searching, I'm more convinced that the book is entirely fictitious, rather than loosely based on a true story. Let me know if you know otherwise.

Update Update: It is indeed entirely fictitious, and the author Yann Martel explains the methods he used to write the story.

It is still a great book.
