This is a general beginners book for Drupal and web development in general. Overall I'd say it is a good book for those wanting to learn about Drupal. My biggest issue is with some of the more generic advice on how to develop a site or how to decide about what you want your site to do. These are just extra elements that I think should be left to a different book.
Still I'd recommend this book if you are interested in learning about how Drupal works and whether you can use it for your site. Combine it with a book on module development that I am currently reading and you have a good round view of the basics of Drupal.
