Under appreciated
Format: Hardcover
I have the first edition, and the 3rd (2020), and the 3rd. This book is a decent introduction to InfoSec, although it takes a few years and some experience to be able to truly appreciate it. I've probably ready it all, in prices, across 15 years and all revisions. It's a reference, it's a guide, that book is my best friend. I think this book is a good guide for entry level folks who are looking for a comprehensive introduction to the field of computer security, and also to senior staff. Be it managers, directors, eng managers, internal audit and privacy professionals looking for a comprehensive introduction to Security relevant regardless of the particular technology they work with or industry they are in.

Highly Readable and Authoritative
Format: eTextbook
I had the pleasure of being introduced to this book by a professor in graduate school. Anderson's book is very readable for those who are getting started with security engineering. I found that going at a pace of a chapter each week or so was good for me to really digest the content. I'm about half-way through! I also recommend ching out the website for the book. It has PDF samples as well.

An absolute must for everyone dabbling with Unity 6 Game Development
Format: Paperback
Half of this book is about C# (until Chapter 6), and the other half is about actually making games. The book is very well written, and it is everything I needed to get a few problems solved with Unity 6 projects. I love how clearly things are explained, and the only thing I wish for is that I was able to spend more time delving into this while maintaining my financial status...

A Seasoned Developer's Fresh Perspective on Game Development
Format: Paperback
Finally, a game dev book that respects your existing programming knowledge As someone who's spent two decades architecting enterprise web applications in C# and ASP.NET, I approached game development with what I thought was a solid foundation. I was wrong—not about C#, but about how differently it's applied in game engines. After five frustrating years of trying to bridge that gap through scattered tutorials and documentation, Harrison Ferrone's eighth edition finally gave me the structured path I needed. What This Book Gets Right for Experienced Developers: The pacing is deceptive. Yes, it starts with programming fundamentals, but don't skip ahead. Ferrone's approach to OOP in the context of Unity's component architecture was revelatory. In web dev, I'd been writing services, repositories, and dependency injection for years. Here, the MonoBehaviour lifecycle and component-based thinking required a genuine mental shift that the book handles exceptionally well in chapters 5-6. Chapter 10's revisit of types and methods isn't redundant—it's strategic. By this point, you've written enough Unity scripts to appreciate why game code patterns differ from traditional enterprise patterns. The discussion of value types vs reference types hits differently when you're optimizing frame rates instead of HTTP response times. The Unity 6 Update Matters: Having struggled with outdated Unity tutorials for years, the Unity 6-specific content is invaluable. The screenshots are comprehensive (full-screen mode can make text small, but the GitHub repo and graphics bundle solve this). More importantly, the code samples reflect current Unity APIs and best practices, not deprecated approaches that still litter Stack Overflow. Where It Shines for Career Transitioners: Chapters 11-13 are worth the price alone. LINQ in Unity isn't just about querying collections—it's about performance considerations I never had to think about in web apps. The coverage of generics, delegates, and events finally connected how Unity's event system relates to patterns I already knew, but in a real-time context where every allocation matters. The serialization chapter (12) bridged my understanding of data persistence from databases and JSON APIs to Unity's PlayerPrefs and ScriptableObjects. This practical grounding is what most tutorials skip. Minor Quibbles: The FPS prototype is solid for learning, but I wish there was more discussion of common anti-patterns experienced developers bring from other domains. I still catch myself over-engineering solutions when Unity's component system offers simpler approaches. Also, while the book touches on performance, those coming from async/await-heavy web development will need supplementary resources on Unity's coroutines and the Job System for more complex scenarios. Bottom Line: If you're a professional developer trying to break into game development, stop collecting random Udemy courses. This book provides the structured progression and context-appropriate examples that respects your intelligence while teaching you to think like a game developer. The C# you know is necessary but not sufficient—Ferrone bridges that gap methodically. After years of false starts, I finally have a working game prototype and, more importantly, the mental models to keep building. That's worth significantly more than the cover price. Disclosure: I received an advance review copy from Packt Publishing. This honest review reflects my genuine experience as a career-changing developer.
