I read 2 of E.J. Pirog's books. 1 on Leopard/Sulcata tortoises. And 1 on Russian tortoises (with a lot on the Testudo species) and I thought they were very informative and very good. They were GREAT for beginners and I would HIGHLY recommend them. They pretty much cover everything from Diet-Health Care- Husbandry-Breeding. I wouldn't recommend it for any tortoise keepers/breeders who are already experienced in housing and breeding and all that. But if not, a very good book
