Sam is a single-handed sailor aboard a minimal yacht. Other than that, he’s a fairly normal guy, not one you would expect a god to notice. Then he says the wrong thing – or the right thing.
This is science fiction set in contemporary yachting, includes an alien world with its own kind of people and offers insight into several gods. It is a spoof on religion – and humanity. That said, it should be taken seriously.
“The Book of Sam” is gospel. As with any Good Book, you can quote it with authority. And it can be opened at random to find the answer.
