The Way Back

Lost in space...lost in time. There can be no more terrifying situation for any spaceman to be in, and such was the problem when Commodore Grimes' Faraway Quest broke free from the mysterious Kinsolving's Planet. Because the universe was vast and they had been out beyond the Galactic Lens. Because time is infinite and they had slipped beyond their own epoch. Because in whatever universe they were in they could raise no etheric word, no telepathic beacon, no other star vessel.
But for John Grimes, a veritable Commodore Hornblower of the future space seas, there had to be a way back. The first step was to locate Earth, the launching place for all humanity. But Earth turned out to be legend and myth and faith - and Grimes' rebellious crew were to enact roles already fabled before they were born.
