Pretty thorough overview, but not quite enough depth to make it more than a beginner's book. Biggest ding on this book (worth docking it two stars) is not being current. The examples provided are not large or complicated enough for it to happen, but if the patterns he outlines are followed by new Angular devs into large/complicated projects would result in scope soup. Not once does he hint at the changes coming to Angular 2.0 and prepare developers by instructing them on it. Too much emphasis on $scope and barely even a footnote on bindToController and he just is not teaching in sync with the way Angular is transitioning. A big reason why there haven't been many new books written on Angular in the last 6 months is because authors don't want to publish something that will be instantly out-of-date when Angular 2.0 (and even 1.4 for that matter) is finalized.
The fact that this book was published a month or so ago and is teaching the material as if nothing in the Angular world between spring of 2014 and now have happened is without excuse. Several of the concepts being taught in this new book are not only out of fashion but are falling into the territory of "anti-patterns" in the Angular world. If you've got time to kill in a bookstore and feel like reading this or if you get this book for free, it's probably worth the read (I admit I did learn several new things), however if you're new to Angular I would advise you to either wait a couple more months until newer Angular books start being released, or find some good online articles instead
On the positive side of things, he is very thorough. I doubt there are any other Angular books out there that list and describe as many of the options and intended usages of built-in Angular services as this one does. Sure, you could go online to the Angular docs to see each method and method parameter listed and their intended usages for something like the $location service, but it's nice to see it in print form and paraphrased as well as this author does. It's certainly worth the extra length to the book to have that more usable reference material.
