Nine Lords of the Night by E. C. Gibson

The author combines academia, archaeology, looters, revolution and corrupt police to create a gripping mystery set in the Chiapas region of Mexico. The disappearance of a female graduate student working on a dig at a Mayan site sets off an involved chain of events. Several story lines move between Harvard and Chiapas and involve graduate students and faculty, a revolutionary called The Professor and some truly evil bad guys. Mayan religion, both historical and present-day, weaves throughout the story. The author does a very good job of describing the jungle and the conditions of the Indians living there after the government's "pacification" program killed so many of them. This is a real page-turner and I couldn't put it down. I recommend this to those who like a good mystery. My only reservation is that I wasn't totally satisfied with the ending. But I won't play spoiler and will leave that to other readers to decide.
