Sozobe, I have not finished Pi but I am enjoying it. It is quirky and the sweet humor of having a child who wants to be a Muslim and a Christian while staying a Hindu is likeable. Of course, as a Hindu, it is more OK to add Gods, so he comes about it the right way.
I adore zebra and don't like bloodshed

The plagiarism accusation comes from another story about a teenage boy, a great cat and a boat. There it apparently ends, though I haven't read the Brazilian book, that's what people seem to say and his Booker Prize wasn't taken away.

In other words, yes. I'd recommend it, with the caveat that I may become disappointed later, when I'm finished.
