Dinner with a Cannibal: The Complete History of Mankind's Oldest Taboo, by Carole A. Travis-Henikoff.

The first two chapters are a bit spine-tingling, but the book focuses more on the history of the religions and societal norms that condone cannibalism, rather than aspects of the physical act itself.
"Cannibalism is not a simple matter, but a complex and multifaceted subject that can tip either end of the moral scale, a sometime custom or singular event that has been with us from the beginning. And while cannibalism continues to be practiced throughout the animal kingdom, it has-- for the most part-- been tossed out of the human closet" (pg. 298). Yet Travis-Henikoff presents evidence that cannibalism, far from being shunned by most peoples, has been an integral part of most societies, and is still practiced around the world, even in "civilized" communities as recently as 2003. Many people would like to ignore or deny cannibalism, recent or ancient, because it isn't pretty, but "a select group of scientists... are trying to replace the rose-colored glasses of recent decades with historical specifics and archaeological evidence," because "political correctness has failed to save a single life" (pg. 223.)

"The truth is, we all have cannibals in our closets," writes Travis-Henikoff in her introduction to this meticulously researched, compulsively readable history of mankind's greatest taboo. As she eloquently illustrates, cannibalism has been around for as long as humans, and it's quite possible that its outlaw is a recent development in terms of recorded history. Many readers are no doubt familiar with the Chilean rugby team immortalized in Piers Paul Read's Alive (recounted again here), but not with the fact that widespread cannibalism has been documented in parts of war-torn Africa as recently as 2003. Sadistic serial killers and the oft-stereotyped tribesmen of the Amazon figure prominently, but where Travis-Henikoff truly excels is in her sociological and anthropological analysis, offering thoughtful insights into the whys of cannibalism, lucidly explaining how cannibalism can begin in a society, as well as its historical employment in times of famine, war and even during a period of political witch hunting in Communist China. A brief but entertaining digression into folklore examines cannibalism in fairy tales such as the Brothers Grimm. Throughout, Travis-Henikoff maintains a thoughtful tone, free of judgment, that frequently challenging readers' beliefs. The result is an eminently enjoyable, albeit very dark exploration of a taboo topic that should give armchair anthropologists, sociologists and historians plenty to chew on.-- Publisher's Weekly starred review.

The author's writing style wasn't my favorite, but overall, it was a very good book. Not for the faint of heart or weak of stomach, but highly recommended.
