When Nash Tabor found the alien living among the Yaqui Indians he was certain that this was the sensational discovery that would end his search for the badly-needed bolster to his sagging academic reputation.

Crippled in mind and body—from a wrong marriage and a severe motor accident—the anthropologist had made this last do-or-die trip to Mexico, never thinking that this discovery would mean not only an end to pain and hunger, but also immortality and power beyond his wildest imaginings.
