Fleeing a carnivorous race of alien monsters, the entire surviving human
population from 500 years in the future escapes into the present in this
thrilling science fiction adventure from one of the golden age greats.
Our human descendants from five centuries in the future are coming to
visit - all one billion of them - arriving via tunnels through time.
Even though the present is merely a stopover and their ultimate
destination is the age of the dinosaurs, their arrival has caused a
worldwide uproar. Some folks want them gone, and some want to go with
them as governments and powerful corporations alike scheme to get their
hands on remarkable, potentially profitable time-travel technology.
There is a dark and terrifying reason, however, for the visitors' abrupt
arrival.
Our frightened descendants are seeking sanctuary from carnivorous aliens
who have descended upon the future Earth, a threat that could mean the
rapid destruction of the entire human race. And the end could come
sooner than anyone imagined, for some of the intelligent, rapidly
breeding extraterrestrial monsters who have been devouring our
children's children may well have followed their prey back to the now.
A speculative fiction master who stands alongside Asimov, Clarke, and
Heinlein in the pantheon of golden age science fiction gods, multiple
Hugo and Nebula Award winner Clifford D. Simak delivers an alien
invasion tale that is at once wildly imaginative, seriously thought
provoking, and just plain fun.
