I found "The Complete C Reference" by Herbert Schildt to be quite good. Most of the language is covered in about 250 pages followed by standard library function, algorthims and data structures and ends in a good project "The Little C Interpreter". Its about 800 pages but then its a reference so you don't need to read it in one go :-)
