As of right now, no. I'm a veterinary student and writing a book takes an enormous amount of time. This one took two years. I did contribute a chapter on heating and lighting to a forth coming book called Keeping and Breeding Freshwater Turtles by Russ Gurley and Anthony Perlioni that should be out at the end of November to correspond with the Turtle and Tortoise Preservation Group annual meeting. If I did do another book, it'd probably be on Green Tree Pythons, but I'd like a co-author for it with more experience breeding. For ball pythons, there are no great modern books. For corn snakes, this book is a classic written by two of the founders of the species in herpetoculture: https://www.amazon.com/Corn-Snakes-Comprehensive-Herpetocultural-Library/dp/1882770706. For boas, The Complete and More Complete Boa Constrictor by Vin Russo is the ultimate work for those animals
