Echo of the Black Chorus

Memory detective Elara Voss has no past — until the night she touches a stolen data-shard and hears her own erased childhood laugh. That sound awakens the truth: she is not human. She is the living key engineered to unlock every mind on the continent and rewrite humanity into one obedient song. With midnight approaching and the city turning against her, Elara must decide whether to destroy the weapon inside her skull… or become the voice that ends free thought forever.

Van Terra

Jasper Van Terra stalks the streets of the city-planet Kronos, masquerading as a supervillain while secretly after revenge on Kronos's governor, the man whose family stole her from Earth and ruined her life. When she's lucky enough to get arrested on the same day as one of his escaped lab experiments, she may have exactly what she needs. Grace Alvarez has cybernetic wings, no memory of her life before the governor's palace, and-after Starr orders her killed-one hope of survival: Van Terra.
