I also watched Firefox at the theater!
Back then I never thought to look for the novelization though, so I never read it or had even
HEARD of
Firefox Down.
Currently about halfway through
Redliners, by the late David Drake.
YEARS back I read another sci-fi story where the plants were against humans as they are in
Redliners, but I don't remember the Author much less the title.
Looking at his Bibliography, aside from reading most (if not all?) of the Hammer's Slammers books, I've read
Ranks of Bronze (which had 2 Sequels I'm
JUST NOW finding out about!),
Dagger (from
Thieves' World),
Killer, and probably some of his other works. I know
Northworld sounds familiar (after looking at the Wiki for it), so I
Think I've read it (when it was
NEW!), but don't think I read the other 2 in the trilogy.
