After nearly a decade away, Nebula Award–winning author Elizabeth Moon makes a triumphant return to science fiction with this installment in a thrilling new series featuring the daring hero of her acclaimed Vatta’s War sequence.

Summoned to the home planet of her family’s business empire, space-fleet commander Kylara Vatta is told to expect a hero’s welcome. But instead she is thrown into danger unlike any other she has faced and finds herself isolated, unable to communicate with the outside world, commanding a motley group of unfamiliar troops, and struggling day by day to survive in a deadly environment with sabotaged gear. Only her undeniable talent for command can give her ragtag band a fighting chance.

Yet even as Ky leads her team from one crisis to another, her family and friends refuse to give up hope, endeavoring to mount a rescue from halfway around the planet—a task that is complicated as Ky and her supporters find secrets others will kill to protect: a conspiracy infecting both government and military that threatens not only her own group’s survival but her entire home planet.
