Amazon.com description: Product Description: Eleven protagonists find themselves skirting the often uncertain boundary between this world and others, by choice, by chance, or by coercion. Warriors fight battles they didn't sign on to fight. Androids grapple with humanity, their own and that of the people around them. Teachers, artists, scientists, and even a housewife encounter realities they never knew existed. From ancient Britain to the moons of Jupiter, from Scotland to Tibet to your own back yard, from this world to the ones that never existed, these eleven stories take you for a wild ride along the rim of time, space, and the imagination.
