When I got the book I was a complete Drupal newbie, but not a complete CMS newbie (I knew a bit of Joomla!).
I followed a 3-day Drupal course and afterwards started reading this book. Even with this course I'll found the book hard to read, so certainly not for dummies.
I also didn't like the style of writing: the authors fly through difficult concepts and are curiously wordy in explaining simple concepts.
On the positive side this book offers you plenty of keys you won't find elsewhere: from customizing themes to building powerful Views and optimizing queries.
But to get the most out of this book, you'll definitely need to know your basics or you'll get lost on the steep learning curve Drupal is known for.
Disclosure: I received a copy of this book from the publisher in exchange for writing this review on behalf of CodeRanch.
