This whole book I just kept asking people who had read it how there could possibly be a twist. Other than the obvious twist which I just kept telling myself would never happen. Then what would be the point of the whole book?

SPOILERS BELOW.

So I was absolutely ENTHRALLED with this book once I dragged myself through the first 100 pages. While Pi's 3 religions were interesting, I never felt that they became relevant enough to his plight to have spent 100 PAGES on them at the start. Until the very freaking end with the twist that is.
The imagery was fantastic, the story itself remained gripping even though I kept thinking what else could there be to write about? He floated around on the ocean and eventually survived. I loved the island with the meerkats, and it broke my heart when he decided to leave.
But then THE END. I couldn't take it. It was one of those books that I closed and literally threw on the couch and walked away. Seriously? Maybe after a day or two of thinking about it it'll grow on me but right now I'm at the point of total despair. He had to invent that whole life for himself to make himself feel better about his situation? I don't begrudge him that but it makes me so depressed. I want to believe the story about the tiger. That's what I want. Done.
