To win an impossible war, Captain Kel Cheris must awaken an ancient weapon and a despised traitor general.

Captain Kel Cheris of the Hexarchate is disgraced for using unconventional methods in a battle against heretics. Kel Command gives her the opportunity to redeem herself by retaking the Fortress of Scattered Needles, a star fortress that has recently been captured by heretics. Cheris' career isn't the only thing at stake. If the fortress falls, the Hexarchate itself might be next.

When Shuos Jedao wakes up for the first time, several things go wrong. His few memories tell him that he's a 17-year-old cadet - but his body belongs to a man decades older. Hexarch Nirai Kujen orders Jedao to reconquer the fractured hexarchate on his behalf, even though Jedao has no memory of ever being a soldier, let alone a general. Surely a knack for video games doesn't qualify you to take charge of an army?  

Thousands of years ago, Earth’s terraforming program took to the stars. On the world they called Nod, scientists discovered alien life - but it was their mission to overwrite it with the memory of Earth. Then humanity’s great empire fell, and the program’s decisions were lost to time. Aeons later, humanity and its new spider allies detected fragmentary radio signals between the stars. They dispatched an exploration vessel, hoping to find cousins from old Earth. But those ancient terraformers woke something on Nod better left undisturbed. And it’s been waiting for them.

Ambassador Mahit Dzmare arrives in the center of the multi-system Teixcalaanli Empire only to discover that her predecessor, the previous ambassador from their small but fiercely independent mining station, has died. But no one will admit that his death wasn't an accident - or that Mahit might be next to die, during a time of political instability in the highest echelons of the imperial court. Now, Mahit must discover who is behind the murder, rescue herself, and save her station from Teixcalaan's unceasing expansion.

An alien armada lurks on the edges of Teixcalaanli space. No one can communicate with it, no one can destroy it, and Fleet Captain Nine Hibiscus is running out of options. In a desperate attempt at diplomacy with the mysterious invaders, the fleet captain has sent for a diplomatic envoy. Now Mahit Dzmare and Three Seagrass - still reeling from the recent upheaval in the Empire - face the impossible task of trying to communicate with a hostile entity.
