Detective Elijah Baiey is called to the Spacer world Aurora to solve a bizarre case of roboticide. The prime suspect is a gifted roboticist who had the means, the motive, and the opportunity to commit the crime. There's only one catch: Baley and his positronic partner, R. Daneel Olivaw, must prove the man innocent. For in a case of political intrigue and love between woman and robot gone tragically wrong, there's more at stake than simple justice.

Breq - the soldier who used to be a spaceship - is serving the emperor she swore to destroy.

Caught up in violence and intrigue, McGill is given the task of finding out where the loot has gone and who was responsible for the theft in the first place.

The Federation's military command is desperate, and with their fleet still in tatters, they make a last-ditch effort to free the planet: They pull Captain Jackson Wolfe out of retirement and put him in command of a ship they hope can get past the defending armada and provide support to the beleaguered Marines and civilians fighting on the surface of the contested world. There is no reasoning with this enemy. If the Terran Federation wants their planet back, they will have to pay the price.
