Shelby Apple, a filmmaker, looks back on his hectic life. He documented wars, lost his best friend & followed a paleontologist on his quest for mankind's source. The story of a 42,000-year-old prehistoric sage Learned Man alternates the story. It took me a while to get used to this because they have such a different voice. What remains is a compelling novel about two men who are both fighting against mortality. But human resilience conquers all.
