Eaters of the Dead by Michael Crichton - This is the book that the film The 13th Warrior starring Antonio Banderas was based on. The film was a flop at the time, but it is slowly gaining something of a cult following. I personally saw it when I was in my early teens, and loved it. I only recently discovered that it was based on a book, maybe due to the fact that it did not have the same title. The novel is very interesting due to it presenting a fictional story, based in parts on an account of a real Arab traveler, like a scholarly work with footnotes riddled all over. It was an attempt a bringing the story of Beowulf down to a fictionalized historic account of an eye-witness, and I guess it was a little too successful at it because Crichton himself mentions in the added afterword that he years later had lost track of which of the footnotes that were real and which he had made up. The story itself is about an Arab traveler who travels with a group of Vikings to fight an evil enemy called Wendol in their homeland in the far North. A great novel.
