Do you mean David Poyer?
It's a good read and references places that most cave divers that have dove in North Florida would be familiar with (white room). A couple of cave divers were technical advisors for it.
Definitely not - the Boon book was published over a decade before.
I’ll look out for a copy of the Poyer novel though, it sounds like it might be enjoyable to read.
