There's 21st Century C by O'Reilly, which I enjoyed. I'm not qualified to say whether you should read it, but there seems to be a lot less backlash towards it than, say, Learn C The Hard Way. My main criticism is that the author wastes half the book on good development practice which is all well and good, but not if you're just there for the C. For developers not familiar with make, testing and so on, it's great. As for the actual C content, frankly this was where I went to when I was wondering how to write better (modern) C, so I don't really know any better. The writing is almost certainly opinionated and as above, could be a lot more comprehensive. (oops edit window left open for a while, see sibling!)
