Cycle of Nemesis

Seven thousand years ago one of Earth's earliest civilizations was confronted by a menace from the stars - and died in a world-shaking effort to destroy that cosmic monster. But the death of that forgotten empire was not in vain, for they did succeed in entombing that dimension-shaking thing out of sight and harm to humanity.

But their efforts could not make that burial permanent - and after seven millennia the monster stirred again, cracking through the time-weakened barriers to assault the new world of today.

This is a stunning novel of time and space, of desperate adventures through lost worlds and future phantasms, as a small band of valiant men fight the shattering power of an extra-galactic nemesis.
