I bought this book a few weeks ago and at first was shocked a little by how thin the book is... however the information provided is VAST and very helpful! I've read a couple of other hamster care guides and this is the best one I've found. One small downfall is the fact that it contains a few american-ism's including an example price list in U.S. dollars but that can be overlooked. The information is easy to take in and includes fun little facts you usually wouldn't find.
I would recommend this book to adults rather than children due to the amount of text and very few pictures. I think it would be especially useful to parents with children longing for a hamster.
An entertaining, helpful, novelty book ... the only reason I have rated it four stars rather than five is that as I mentioned earlier it only contains a couple of photos, which are black and white. Although the book does contain a list of helpful websites, most with cute pictures on them.
All I can say now is enjoy the book!
