I'd like to recommend the following two books for beginner turtle keepers:

Turtles and Tortoises: A Complete Pet Owner's Manual by R.D.Bartlett and Patricia P. Bartlett.

The Complete Idiots Guide to Turtles & Tortoises by Liz Palika

Both books have lots of great ideas and suggestions for keeping your turtle healthy and happy. The Bartlett book has great photos.

Happy Reading!!
