A Case of Conscience, by James BlishRead about another entry on the list.
This Hugo Award-winner sends a Jesuit scientist on an expedition to an alien planet inhabited by a reptilian creature. The aliens aren’t technically dinosaurs, but no one told the cover artists that. The dark book dives into issues like the connection between religion and logic, what constitutes heresy, and planet-wide demonic possession. Check it out if you’ve always wanted a good dinosaurs vs. Catholics story.
