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.

Deep in space lies the black hole known as Angelmass, so called because it emits enigmatic particles with the unusual ability to render humans calm, reasonable, and incapable of lying—which would normally be seen as a good thing. But not by everyone. Academic Jereko Kosta is pressed into service by the Pax to spy on the Empyrean, joining the crew of a ship actively hunting the particles. But what he learns turns out to be both scientifically fascinating and morally frightening.

On Tigris, children develop telekinesis beginning at the age of five. By the time they're pre-teens, though, their special abilities peak, then slip away as they reach maturity. Being able to "teek" gives them power—even over most adults—until they gradually become regular teenagers, no longer special, no longer with authority and status. Some handle the Transition better than others.
