These short stories differ from my earlier work both in terms of destinations and templates to get there. Time travelers arrive in late 18th century Ecuador to warn of an earthquake that will destroy a village, in late 19th century Michigan to help an inventor fly before the Wright Brothers, in late 20th century Poland where a modern day Rip Van Winkle has missed the collapse of the Soviet bloc, and 40 years into the future where an unknown man learns of his posthumous fame. Imaginative templates include a unusual wormhole in distant space, an elevator in an abandoned coal mine shaft, a deserted Canadian lighthouse, a race car with a jet engine, harsh weather on the slopes of the world’s tallest mountain, an antique radio, and error on an alien mothership.

If time travel has already taken place, has it on balance improved or harmed the human condition?
