during a seemingly normal spacewalk, it leads to disaster: The shuttle is
destroyed - completely baseless until the bond between them spins Stone and Kowalsky
completely alone in the darkness. Due to the deafening silence they know that
they have lost contact with Earth ... and thus any chance of rescue. Her fear
