I'm so much into Domain-Driven Design! I already read Applying Domain-Driven Design and Patterns and I just finished reading Domain-Driven Design: Tackling Complexity in the Heart of Software from the DDD guru himself. If you should read one book about software design, than this one is definitely it.
The only downside of these rather abstract books is their lack of (real-world) examples. I'm glad that Tim McCarthy is writing a book with the intention to clarify this complex subject. A case-study of a real-world application that uses Domain-Driven Design concepts should do the trick. I'm looking forward to read his book and get some insights about how others are applying the DDD techniques. I'm eagerly reading the Domain-Driven Design Yahoo group to feed my brain and I already learned a lot from the people there.
