The Heechee Saga

When prospector Bob Broadhead went out to Gateway on the Heechee spacecraft, he decided he would know which was the right mission to make him his fortune. Three missions later, now famous and permanently rich, Robinette Broadhead has to face what happened to him and what he is...in a journey into himself as perilous and even more horrifying than the nightmare trip through the interstellar void that he drove himself to take!

Frederik Pohl was on a streak when this Hugo Award-finalist novel was published in 1980. Now back in print after an absence of nearly a decade, this unique science fiction novel is as fresh and entertaining as ever. The story begins when the hero of Gateway finances an expedition to a distant alien spaceship that may end famine forever. On the ship, the explorers find a human boy, and evidence that reveals a powerful alien civilization is thriving on a transport ship headed right for Earth....

After millennia had passed, Mankind discovered the Heechee legacy (an alien culture that fled to the relative safety of a black hole) - in particular an asteroid stocked with autonavigating spacecraft. Robinette Broadhead, who had led the expedition that unlocked the many secrets of Heechee technology, is now forced once more to make a perilous voyage into space - where the Heechee are waiting. And this time the future of Man is at stake....

Advanced Heechee technology had enabled Robinette Broadhead to live after death as a machine-stored personality, enjoying his life by flitting along the wires from party to party with a host of other machine-people. But suddenly his decadent existence ends when an all-powerful alien race intent on the utter destruction of all intelligent life reappears after eons of silence, and threatens the lives of all heechee and humans.
