When I first read the DDD book almosty 15 years ago, I think it took me 2 or 3 reads to get it into my head. I really like the first half that can be used purely for a design perspective, and the second half for communicating with the business people to do business domain modelling .
Other books I really like are
The Design of Everyday Things by Don Norman, it is a good read and lets you talk to a lot of UX'ers as I have found more than a few that have used this book for their thesis.
Enterprise Integration Patterns by Gregor Hohpe and Bobby Woolf, which is old but in world of streaming procesing a lot of the patterns can be reused.
