Michael Bradley, highly respected researcher for National Treasure and The Da Vinci Code movies and author of two prior books on the Holy Grail, completes his best-selling nonfiction trilogy with Swords at Sunset: Last Stand of North America's Grail Knights. Drawing on extensive research, the Book of Mormon and ancient artifacts (the book has many photos), Bradley contends Grail refugees fled Europe's Inquisition, spread through North America, and met their end in Niagara and Vermont. Original.
