Ok, I'm am really stuck on this one.
I Cannot recall the title, or author if this book, but it strikes me as in the mid-to-late 70s? Perhaps early 80s? And for the life of me the Internet has given me no leads.
The gist of the story is:
- Colonists on alien planet are trying to terraform it, while living in these massive bio domes.
- Things are not working too well, everyone getting sick, going insane.
- The main character (who is also a rapist as we learn from the opening scene), takes off on a future-bike and crashes into an alien swamp. After breathing the air (spending a huge amount of time hallucinating himself as a God, running around naked and insane), he goes back - forcibly rounds up anyone that believes they'll live if they step out of the bio-domes and murders the unbelievers / sick ones.
- It ends in a fairly grisly manner with the survivors being dubbed 'The First Gods'.
- I recall a good deal of focus on Celtic or Norse gods.
- The idea of trusting the natural world to sort out the "adaptation" issue was big in this.
What is the name of this book?
