This book is a useful companion to the Eric Evan's original "blue book" on Domain-Driven Design. Millet and Tune flip the order of Evan's book, discussing strategic patterns (bounded context, context maps) before the tactical ones (entities, aggregates, repositories ...). Particularly valuable are the additions of DDD-thinking emerged after the publication of the blue book, like events, event storming, and event sourcing.

The book is full of examples, all in C#, also relying on C# libraries. Nevertheless, the examples are also sufficiently accessible for developers using other languages.
