Oath Written in Star Ash

She was born to witness the truth. But in this empire, truth is the first thing they erase. Avra Nightglass, heir to a powerful noble house, saves Riven — a chained prisoner condemned as a plague, a monster, and a crime against the throne. The empire claims he has no name, no past, and no bloodline worth remembering. But when forbidden star-fire awakens inside him, Avra realizes the man everyone fears may be the last proof of a royal secret buried beneath centuries of lies.
