Jessamy's life is a balance between acting like an upper class Patron and dreaming of the freedom of the Commoners. But at night she can be whomever she wants when she sneaks out to train for The Fives, an intricate, multilevel athletic competition that offers a chance for glory to the kingdom's best competitors.

In a corporate-dominated spacefaring future, planetary missions must be approved and supplied by the Company. Exploratory teams are accompanied by Company-supplied security androids, for their own safety. But in a society where contracts are awarded to the lowest bidder, safety isn’t a primary concern. On a distant planet, a team of scientists are conducting surface tests, shadowed by their Company-supplied ‘droid—a self-aware SecUnit that has hacked its own governor module, and refers to itself (though never out loud) as “Murderbot.”

In the past, humans were the dominant star-traveling species in the universe—until the Chapalil came, conquered, and absorbed the Earth into their intergalactic empire. One of the only humans ever granted nobility by the Chapalil, Charles Soerenson once led a failed rebellion against the alien overlords. Now his sister, Terese, has abandoned her homeworld, impelled by a broken heart to seek a new life among the worlds her brother rules. On Rhui, a planet off-limits to interstellar voyagers, Tess stumbles upon a dangerous Chapalil conspiracy.

Torn by internal strife, Wendar faces deadly raids from the north by an inhuman race, the Eika. And now terrifying portents are being seen; old ruins restored to life under the light of the full moon and peopled by the long-vanished Lost Ones; dark spirits walking the land in broad daylight. And suddenly two innocents are about to be thrust into the middle of the conflict.

With their vast cargo holds and a crew that could fill a city, the Greatships are the lifeblood of human-occupied space, transporting an unimaginable volume - and value - of goods from City, the greatest human orbital, all the way to Tradepoint at the other, to trade for xenoglas with an unknowable alien species. It has always been Marca Nbaro's dream to achieve the near-impossible: escape her upbringing and venture into space.
