A book about water, and being submerged in it?

Question

I've run into a small wall on a book I'm reading.

A chapter discusses how when a character in a novel goes into/under the water (the sea, lake, pond, river, pool) it probably symbolizes them being reborn or baptized.

I can't think of a book that involves this.. any suggestions??

I considered Huck Finn but couldn't think of a specific example.

Answer 1

The Bible.  

Answer 2

A Perfect Storm

Answer 3

think outside the box
