Poul Anderson 
Starfarers 

Courageous space explorers embark on a mission to make contact with alien races light years away, while the Earth they leave behind ages twelve hundred centuries It’s the most exciting discovery since humankind first began watching the skies: SETI scientists detect starship “trails” in a galaxy many light years from Earth, and at long last the dream of human-to-alien contact is attainable. But the courageous crew of starfarers assembled to take on the monumental endeavor must sacrifice the only lives they’ve ever known and the people they love; the Earth will have aged many thousands of years when—and if—they are finally able to return. Still, their hunger for knowledge of the universe and the extraterrestrial races that inhabit it is too great to deny, and the Envoy rockets off into the vast unknown. It’s a perilous mission that will profoundly change everyone it touches—even as the passing millennia transform the Earth in ways no one could ever have imagined.   Of all the science fiction extrapolators to emerge in the twentieth century, none were more visionary and few as prolific as the great Poul Anderson. Starfarers, his ingeniously imagined space exploration adventure, still stands tall among the most intelligent, enthralling, and unforgettable science fiction novels ever written.   This ebook includes the bonus stories “Ghetto” and “The Horn of Time the Hunter.”
