Well, one book that gets tossed around a lot is _C Unleashed_ by
Heathfield, Kirby et al.

Apparently it has been out of print for a few years but both new and
used copies seem to be still available on sites like amazon.com

See the thread titled "C Unleashed" started by Joe Wright.

One another book is _Expert C Programming_ by Peter Van der Linden.

You might also consider books on system programming and programming for
specific systems like Unix, Windows etc. Also you might consider books
like _UNIX Network Programming_ by Stevens. I know these are not about
C per se, but they do use C as their language and illustrate fairly
advanced programming tasks.

IMO, yes.
