Book excerpt: Jimmy the time-traveler, while trying to solve a time-riddle his late father left for him, gets accidentally flung back in time, to the year 1871, the days of the Wild West, landing squarely in the middle of a valley of death. He stumbles into a pack of gun-toting rustlers, who capture him. To Jimmy's luck though, the youngest of the rustlers, Kit Fisher, is not like the rest of his folks.
