The K&R book is a great example of clear technical writing, but it's also quite terse. I'd recommend C Programming: A Modern Approach by K. N. King instead, as it uses a more gentle pedagogical approach.

That's not really a “but”; eschewing superfluous verbosity is a hallmark of good technical writing.
IMO, a more significant strike against K&R, which is excellent for its time, is that it is hopelessly dated—unless there is a third edition I am not aware of—providing, in the second edition, a preview of the first edition of ANSI C, which was standardized just after it was released.
