Three-time Hugo Award finalist Yoon Ha Lee returns to science fiction with a swashbuckling space opera fighting against an evil empire trying to erase history.

In the stars-spanning Censorate, languages other than the Republic’s own lingua rubra, which has reality-altering properties, are forbidden. Nevertheless, there are discrepancies. The Censorate’s star forces are called the Athenaeum Navy, and each of its ships is referred to as a codex. Instead of port and starboard, its soldiers refer to verso and recto. The unholy “stigmata” gouged into the ships’ hulls might, to a foreign scholar, bear a resemblance to verboten texts in other languages.

The Censorate is ruled by its Peacock, Aurelia, feared for the power of panopticon: she can look through anyone’s eyes. Moreover, Aurelia’s mastery of lingua rubra lets her force anyone who can understand her to follow her orders. Valentina, sold to Aurelia’s family as a child to be Aurelia’s oath-sister and companion, is its Swan, responsible for extracting useful information from foreign texts, then destroying them as well as entire languages through arcane arts. Valentina is assisted in her work by lower-ranking linguists and AI assistants who accept temporary contamination by foreign languages as a necessity of their work.

But this isn’t enough for Aurelia. She wants to control and deploy the Censorate’s thousand-year traitor and prisoner, the Basilisk, a man with a gaze so lethal that he destroyed its fleet of old through camera feeds. Unfortunately for her, the Basilisk gave himself a form of aphasia that makes him immune to her commands.

LOCUS AWARD WINNER • In this explosive sequel to Moonstorm, teen mecha pilot Hwa Young returns to her rebel roots to fight against the Imperial forces—but, as she grapples with her warring allegiances, who can she really trust? Perfect for fans of Iron Widow and the Skyward series!

Hwa Young and her pilot comrades have betrayed the Empire to save it from its own destruction—but what comes next? It’s been just two months since the lancer squad stopped imperial forces from deploying a devastating singularity bomb and taken shelter with the rebel clanners, who have kept them busy with raids against their ex-leaders. Their mission have helped numb the shock of recent battles… for now.

Meanwhile, Hwa Young’s best friend, technician Geum, has been left behind on the imperial fleet, imprisoned for aiding Hwa Young’s deceit against the Empire. Hwa Young is desperate to retrieve Geum—but Geum is slowly realizing that Hwa Young’s loyalties aren’t as clear cut as zie once believed.

As Hwa Young delves deeper into the rebels’ inner circles, she soon realizes that the clanners are just as cutthroat as the imperials, leaving her to wonder who she can really trust… and at odds with Geum, the one person she thought she could count on.
