Decades after a successful invasion of Earth and the Terran Democratic Empire by the Ryqril—hostile, leathery-skinned aliens—resistance fighter Allen Caine is training for an undercover mission. He will assume the identity of an aide to the senate—part of the government that colludes with the invaders.

En route to far-off stars, Toby’s consciousness has a crucial mission: inhabit his clone long enough to repair a spaceship, then zip back to Earth. He’s done it a million times, more or less. OK, twelve times. It should only take a few hours. Until he wakes up in jail. And he’s not alone. His fellow prisoners: a cadre of alien soldiers. His prison: an ethereal boundary that will imprison their spirits until their bodies die. His jailers can’t even see him. But their pet cat (er, iguana cat?) can—and it’s got a serious case of the zoomies.

The universe is a dangerous place, a fact violently brought home to Frank Compton for perhaps the thousandth time when a stranger delivering a message dies right in front of him. An operative for Western Alliance Intelligence until his whistle-blowing activities got him fired, Compton is now being sought out by the Spiders, the robotic alien beings responsible for the upkeep and operation of the Quadrail transportation system, which connects the galaxy's twelve inhabited empires.

Timothy Zahn shows an unparalleled mastership of science fiction in the fifteen tales gathered here. "The Price of Survival" features an alien ship that arrives in our solar system without hostile intentions but with a desperate need whose fulfillment could destroy humanity. "The Giftie Gie Us" tells the story of two lonely survivors who find love among the ruins of a post-apocalyptic United States. And in "Pawn's Gambit," a human and his alien opponent face off over a game that will decide which one of them will return home.

Damon Lathe and his blackcollar combat team face their most serious challenge. On one of the conquered human colony worlds is a Ryqril tactical center through which flows an entire sector's worth of military data. If the blackcollars can find a way inside, it could tip the balance in the current Ryqril-Chryselli war. It could even start humanity on the path back to ultimate freedom.
