Hi,
If you're looking for books on history, Jonathan Fenby's The Penguin History of Modern China is a good starting point in my opinion (it covers about 1850-2000). The Great Chinese Revolution from John King Fairbank is another good option, though it has more of an emphasis on thought history.
Besides that, it depends on what specifics you might be looking for

I found Kissinger's book rather interesting, as well as some biographies - but they might be more interesting after reading one of the more "general" historic books.
