Good, though demanding, overview
Whatever the title may suggest, this is not a book for engineers looking for applications. If interested in analysis and the theory of integration, though, it is a good idea to give this a try.
The book is well structured and the prose clear. Yet it must be said that the style itself is also quite terse. This is a graduate textbook, and it says something about the style that the exercises are never questions or numerical problems. They are claims of the form "A, B implies C" which are to be proved by the student. This is not Kreyszig, so to speak.
