Violet and her Tactically Enhanced Space-Combat Light Armor, Solaris, are adrift in space. After his mother's death, Lucien stands against the most powerful Order to clear his name.
Seraphine isn't spliced, a popular trend among her peers that alters their genetic code with characteristics from animals and reptiles. Damian finds his soulmate among the hostages when his app-connected ring turns gold. Light's return to pro gaming puts close relatives in the crosshairs.
They're all just trying to stand in the light, but that means casting shadows.
