A simple and well written book from Robert and Stephanie that contains not only Drupal 7 essentials but also all other things you need to know to create and run successful Drupal powered website including collection of requirements, selecting a host, selection and installation of components, setup for development, staging and production. Authors exhibit extensive Drupal experience and the book is full of useful tips yet it is written in very accessible and pragmatic manner that will not cause you head to explode from information overload.
I would recommend this book to anyone who is new to Drupal, evaluates upgrading from version 6 or is seasoned CMS designer who wish to learn about Drupal's power.

What I liked about the book:
- Simple and to the point explanation of the subject
- Examples with plenty of screenshots
- Access to author's website with super user privileges
- Tips going beyond scope of simply setting up and running CMS
- Excellent and complete theming tutorial
- Links to many resources for further study

What I did not like about the book:
- It gives away secrets of the trade that creates stronger competition :)
- It refers to modules that are not yet ported to Drupal 7 but I recon that is only matter of time when they will and it is good to know about them anyway.

Overall, I was very pleased to see this book being published at the right time when Drupal 7 was released and it being a comprehensive reference and set of easy to follow tutorials.
