Just to give a comparison, paleontologist Dave Hone wrote a bunch of books on dinosaurs such as "Tyrannosaurus Chronicles" and "The Future of Dinosaurs", which aren't academic texts but are pretty good stuff for a non paleo-person to understand the animals. Maybe something like that about snakes?
Another comparison would be "Emperor of all maladies" by Siddhartha Mukherjee, who explained Cancer in pretty good depth in his book.
You get the point- pretty detailed but not academic books.
Thanks!
