Toward Ecosophy

It's impossible to give a list without knowing something about the individual who asks for it! Any novel that makes you think will help build your mental sheath. If it's the kind of forgettable popcorn reading that you read and then barely remember a week later, it's not useful for this purpose, but if it's the kind of story that you think about afterwards, remember vividly, and even reread from time to time, then it's doing the job.

Can you name some novels and some genres that you like? With that as guidance I might be able to be a little more specific.
