Modula-3 is a little known language, but was highly influential on the design of Java. Although the language itself is of mostly historical interest now, this book is a wonderful introduction to a principled approach to both language and software design. Chapter five on threads is still the classic introduction to the topic. Chapter six is a wonderful case-study in rigorous, object-oriented design. Chapter seven is a great tutorial on building complex, multi-threaded libraries.
If you want to be a serious programmer, you have to read this book.
