Query: One of the key books for an enjoyable Cambodia trip

This book proved great for navigating Cambodia. While some of the information is, inevitably, a bit dated, it did help me get around much easier than if I was left to my own devices.The other books that helped me a lot wereGuide to Cambodia: The Temples of AngkorandAngkor Essential: four articles about Angkor past and present.Finally, to really appreciate what life in ancient Angkor was actually like, I strongly recommend a novel,God King of Angkor: A Novel of Tyrannyby Gregory A. Waldron. It's a great epic and I couldn't put it down.
