This is a very broad and basic overview and if you are a beginning hobbyist, this book will provide the groundwork and basics for pet ownership of a Crested Gecko. However, someone looking for more detailed specifics, will need to pick up a more comprehensive volume. This book is 69 pgs long, inc. bibliography, so each chapter is about 6 pgs long - large print, with lots of large photos and the pages being about 5.5" x 8.5" - so not a lot of text. The text that is here is good, clearly written, and helpful, but repetitive, and as I said before, very basic. For example, the feeding section could have been longer, and the Health and Diseases chapter is only 7 1/3 pgs long - but with section breaks, photos and large font headers, it's precious little info. A section on Crested Gecko behavior would have been nice too. The sections on housing, diet, breeding, are pretty good overviews. Certainly enough for a beginner, but if you're going to seriously get into Cresties in a big way, in breeding, raising, etc. PLEASE get other books. I also must say that the photos are excellent. Lots of great full color pics of just about every type of color/pattern of Crestie, and good photos of housing set-ups, nests, etc. So, in summation - very nice beginner's book, but may leave you wanting a lot more depth.
