Sure, but that is meant as a personal thing and not meant as a general statement. Everyone should evaluate whether the book (any book) works for their needs.

The main reason is that, it was a very dry read with various rules and syntax etc and I got bored looking at it quickly. It almost felt like I am reading an abridged version of the standard itself. The exercises didn't appeal to me much.

I didn't mean to dis the efforts of the author at all. There is no other book that covers the modern parts of the standard well. I am not aware of any other C book that covers the wide chars than this book.
