I thought that it was a good book but that there where some holes in the plot. It was pretty confusing at parts but it usually explained them before the chapter ended. It was very in depth so the plot holes are to be expected. It had a good plot with many unpredicted turns but with some things to be assumed. I would not recommend it to people who are squeamish because there are several very violent and gory parts. It does take a while for it to get interesting so you have to be ready to go through about 100 pages of set up.
Over all I would say The Life of Pi is a good book that has some plot holes, is kind of confusing, is in depth, and is fairly violent.
