ARROWHEADS AND H BOMBS
Time-travel for archaeologists was a well-guarded secret; but when the remains of an interstellar spaceship are uncovered along with the usual fossils. the time agents must call on a modern Apache Indian, Travis Fox. to guide them in the ways of his ancestors in their trip to the past.
But the explorers become trapped in space as well as time, on a mad journey on an automatic starship: not even Travis Fox can tell whether any of them will ever see Earth again.
Travis grabbed at the protecting bands on his chair... The ship no longer felt inert and drifting - she was coming alive... Travis lay back, watching the vision plate. Now that the bright glare of the sun was gone he could pick up a smaller dot, for smaller than the star which nurtured it.
"Something tells me, boy," Renfry said in a small and hesitant voice "That's where we're going."
"Earth?" A warm surge of hope spread through Travis.
"An earth, maybe - but not ours."
