Aisha Un-Haad is out of options. Her parents are dead, her brother is dying of a terrible disease, and her sister is about to start working in the dangerous dyeworks. Without money, their lives will get exponentially worse. Aisha does the only thing she can: surrender her freedom to become a mechanically enhanced soldier. Called Scelas, they are living weapons for the oppressive regime that rules the fleet of generation ships on which the last humans live.
Key Tanaka has little memory of her life before becoming a Scela or what drove her to undergo the life-threatening procedure. Aisha wants to protect her family, and Key to unlock her missing memories. In order to do that they and their teammates, willful Praava and awkward Woojin, must join the ranks of the Scela elite. But what happens when they’re ordered to kill, maim, and conspire against citizens at the behest of a corrupt leadership? Body horror, issues of consent, and body dysmorphia abound in this tense novel.
