A Town Is Drowning — Frederik Pohl

It was a pleasant little town in the Northeast. It had never been hurricane country. When they heard that Diane was coming, they couldn't really believe it would harm them. And the hurricane itself didn't touch them.

But the rains caused by the hurricane ravaged their little town as viciously as the worst artillery attack could have done.

This is a powerful and tremendously graphic novel of people trapped in that town: and how they learned what a flood really means.

And how they found out what they themselves were like.
