Jack McDevitt’s 1986 debut novel The Hercules Text is a (then) near-future First Contact story. The Hercules Text was the seventh novel in the Third Ace Science Fiction Specials series, edited by Terry Carr.
Personnel functionary Harry Carmichael has neither the love of his soon to be ex-wife, nor the respect of the scientists he provides with invaluable administrative services. He can at least look forward to distraction from his personal problems. Humanity is about to be contacted by extra-terrestrial intelligence.
Humanity may be about to go extinct.
