Long before "The Revenant" there was "Lord Grizzly," Frederick Manfred's novel retelling the true story of Hugh Glass. He was the frontiersman who survived a grizzly bear attack only to be left for dead by two trappers who were with him. Despite his injuries he crawled 200 miles back to the safety of the nearest settlement driven by the need to extract revenge on the renegades who abandoned him. "Lord Grizzly" was acclaimed when it came out in the 1950s, but attempts to make it into a film failed. Now Manfred's family is holding a reading May 10th to remind people of the book, and to introduce it to a new generation of readers.
