The Killing of Worlds (Succession, 2) [Westerfeld, Scott]

Cut off by an Imperial blockade of the planet, a Rix compound mind has guided a lone Rix commando, Herd, a single warrior backed by the intelligence of an entire planet, and pitted her against the Imperial army in a desperate attempt to break the blockade.

Ten light-years away, a deadly game of political intrigue against the Emperor plays out in his war council. One senator suspects the Rix mind has found a hidden weakness, a secret so dangerous to the Emperor that he is willing to countenance the ultimate crime. . . .

The killing of worlds.
