I own many turtle books, but this one is truly outstanding and is in my "most used" category..... a cornucopia of practical information that is well-written, well-presented and well-researched. There is stuff here that you'd have to combe through an entire library to find otherwise. I commend this text to all keepers, from beginner to professional. It has been called the "bible of turtle keeping" for good reason - there is no better single volume source of accurate information available. The author is founder of the Tortoise Trust, one of the world's leading turtle conservation and education organizations, and is known for numerous contributions to our knowledge on this topic. Without doubt, this is the most useful, practical turtle book I own, and I urge other keepers not to pass it by! There are some awful books on turtles out there, and they can get your animal's killed... this one is quite the opposite, and it has certainly saved many of my own animals. Excellent.
