Highway of Eternity (Unabridged‪)‬

Two present-day investigators race across time to escape malevolent aliens from the future and their terrible "gift" of immortality in this science fiction classic.

What is the price of eternal life? Secret agent Jay Corcoran is about to learn the answer when his investigation into an inexplicable disappearance carries him and journalist friend Tom Boone hundreds of years into the past. Corcoran and Boone's powerful extrasensory abilities lead them to an advanced transportation system through time and back to the bucolic 18th-century English countryside. There, they discover a family from the distant future that is hiding from the Immortals - an alien race that, many centuries on, is seducing human subjects with the promise of immortality. But the cost of life eternal is the corporeal self, and there is no place in the aliens' future for anyone unwilling to exist as mind alone.

Now that the Evans family's sanctuary has been breached, escape is the only answer - for Tom Boone and Jay Corcoran as well - and the only way out is forward...far forward. But racing through space and time can be a hazardous occupation, especially with monstrous beasts, killer robots, and Immortal body destroyers waiting at every juncture.
