The discovery of a remarkable alien technology light years from Earth could have devastating consequences for humanity in this science fiction classic by the author of the Hugo and Nebula Award–winning novel The Forever War

In the far future, the accidental scientific breakthrough known as the Levant-Meyer Translation changes everything. Suddenly people can leap instantaneously across the universe, albeit temporarily, enabling teams of Tamers to explore far-flung worlds and prepare them for possible human habitation. But one expedition doesn’t make it back alive.

Jacque Lefavre achieves his lifelong dream of becoming a Tamer when he joins the Agency for Extraterrestrial Development. On his first exploratory mission to a planet known as Groombridge, Lefavre and his team encounter something truly extraordinary: a small, nonsentient creature that, when joined with another of its kind, creates a telepathic “bridge.” But exploiting this psychic link could bring unanticipated perils, for it is about to bring Lefavre and his team into dangerously close contact with the L’vrai, an ancient, advanced, and hostile race of star travelers—an encounter that could prove to be the first step in humankind’s salvation . . . or its doom.
