The Memory Cathedral

In a magnificent and daring new novel that triumphantly blends fact and fiction, Jack Dann offers his own thrilling secret history of a lost year in Leonardo da Vinci's life. He begins with a wildly imaginative bit of speculation: What if Leonardo, who was obsessed with flight and who conceived brilliant blueprints for the first flying machines, didn't stop with his designs? What if, during that missing year, he actually built and flew his marvelous machine... five hundred years before the Wright brothers legendary flight at Kitty Hawk?
