Compared to the online help, this book reviews favorably. But Revit is a deep program, and to really use Revit efficiently and fully takes more than an "intermediate" book will offer, which the Aubin text admits to being. I say the text is verbose because, for instance, it always refers to Revit as "AutoDesk Revit Building", which gets very tiring. The book introduces Revit by designing two projects, which is nice, but a lot of the useful information is hidden in little sidebar tips, which makes using the book as a reference (for instance, as a command reference) difficult.
