Agreed. The Soul of a New Machine is my personal favorite but I think Mountains Beyond Mountains as well as Strength in What Remains are the more powerful and interesting books.

House was also a wonderful read. In many ways I enjoyed it more than SoaNM due to the parallels with software development but in a completely different domain. Building a house is remarkably similar to building an application.

His whole catalogue is fantastic really. Definitely a favourite author of mine.
