Well I have a few...hahah, I'm really nerdy so it may not be EXACTLY what you're looking for...here's some:
Venomous Snakes of the World - Mark O'Shea (he also has a Boas and Pythons of the world too!!!)
The NEW Encyclopedia of Snakes - Chris Mattison (and yes, I have his old one and his new one haha)
Life in Cold Blood- David Attenborough
The Selfish Gene- Richard Dawkins
River out of Eden- Richard Dawkins
Either the Complete Ball Python or Complete Boa (Kevin McCurley/ Vincent Russo) are great reads, though obviously specific to what the names imply.
There's a couple.
This is coming from a guy that reads Bio books...for fun...soooo yeah. Hahah.
