Any question answered...

I posted this here, but it's drifted down a couple of pages with no suggestions, so I thought I'd repost my question here for a wider audience:

In a couple of months I will be travelling to Cambodia with work, but I have little more than a passing insight into the recent, tortured, history of the country. Can anyone recommend any interesting, accessible books that might give me some more insight into the history of the KR, how it came about, it's legacy and how Cambodia has transitioned towards it's current government?

If the book happened to give some insights into the current social and political institutions and how they function, and the issue of land rights and tenure then that would be a plus but I'd put my emphasis on an interesting and accessible modern history of Cambodia and the KR.
