Does anyone know of any really good books on Scorpions? I have some decent knowledge, have been keeping Scorps for a long time and had a lot of them, but only really have had access to very basic species as I just recently discovered the whole community and all that...but I really want to learn more about all the different types of Scorps. So can anyone recommend a book? I have one book I am currently reading, called "Scorpions" by Manny Rubio, but am looking for some more. Any help would be appreciated!
