In this, our third volume of Robert Silverberg Ace Double novels you get some of his best stuff. “Invaders from Earth” is a great tale about an outer space scam gone horribly wrong, with the fate of an entire world hanging in the balance. In “Collision Course,” the discovery of another, more-advanced race shakes the very foundations of humanity, with a clash of intergalactic powers seemingly inevitable. “The Silent Invaders” throws one man into the middle of a three-pronged conflict that has Earth seemingly threatened by one race, while secretly being imperiled by another. All three tales are perfect examples of why Ace Books was the one-stop shopping place for thrilling science fiction. Also included in this volume is an updated Silverberg Ace Cover Gallery, showing the wonderful artwork that accompanied all twelve of Bob’s Ace novels. Featured are two of the best science fiction artists of the day, Ed Emshwiller and Ed Valigursky. Lastly, as we did in our first two volumes, we’ve thrown in a Robert Silverberg bonus tale, “The Songs of Summer,” not seen in print in decades, complete with its original Kelly Freas illustration.
