For the Japanese historical perspective on Chinese characters (they imported them around the year 400-500 CE), Christopher Seeley is probably the world's leading expert - I have begun reading his essay A History of Writing in Japan, and its suitably thorough.
For the Chinese perspective, a good summary of the whole history of the characters (from seal script onwards) is given in the opening pages of The Complete Guide to Japanese Kanji, again written partly by Christopher Seeley. It's around 7 pages long, if I recall, so it may be insufficient for your needs.
Do tell me if you find just the book you need in the end.
