As the other reviewer said, this is a very solid, good book. Dare I say refreshingly good. I also echo the previous reviewer's sentiment about the tone that the author takes when speaking to the reader. Some people enjoy comical books but I am not one of them. I read books for information, if I want to laugh I'll open xkcd.
Where this book really fills a void is that it assumes you have some experience and maturity under your belt as a programmer / engineer. This is good because it allows us to get down to the meat without hesitation and begin discussing more serious things. What this book is NOT is a book on how to implement a game engine. What it IS is a book on what's in a game engine and common problems and pattern that occur in game engine development. A toolbox of game engine development, if you will. For each chapter / topic, the author devotes some time to explaining the role of this aspect of a game engine and then quickly proceeds to breaking the component down into smaller pieces, discussing common issues, algorithms, and patterns that arise for said system. For example, when discussing memory usage there is a great discussion of a variety of different memory allocators that can be useful in various situations. Almost always the author supplements these discussions with real-world examples of where such a data structure, algorithm, or method was used in an actual game and why.
Another aspect of this book that I really really appreciated was the inclusion of references directly in the text. Since, after all, the book is light on implementation details often the author would conclude a section by saying "So and so has an excellent paper discussing this topic in more detail at ." This is great because it allows the book to still provide access to all the implementation details without actually putting them in the book. So it's not like you're actually missing out on anything, you just have to go to the link.
The book is thick, and has a strong and serious hardback binding. It feels like it will last a long time. I don't think it's necessarily the type of book that you will refer to over and over throughout your game development career, but it offers a great bird's eye view of the entire process, while still allowing you to zoom in on specific areas and get a little bit more detail (or a lot more detail if you follow the links to the external references).
There are a couple minor errors in the book, but they are not that serious and I assume they will be corrected in the first errata and/or second edition of the book. They do not significantly detract from the overall quality of the book however, so I give it 5 stars anyway.
This book was definitely a pleasant surprise, and I only wish more authors would stop filling their books with fluff to hide the fact that they don't have enough information to fill the book. This book is packed with information, with zero fluff, and I definitely recommend it.
