In the empire of Auren, every soul is born marked, a name written in living ink on the left wrist, pointing toward the one person the Registry has chosen as their match. For most, the system is sacred. For Registry Scholar Naia Solven, it is a wound she has spent seven years turning into a career.

When the Registry begins to fail, thousands of marks fading overnight across the empire and leaving citizens unmarked and afraid, Naia is assigned to investigate alongside Commander Daven Kairu, the empire's most disciplined soldier and a man who has kept his wrist covered beneath a Veil Oath for a decade. What neither of them knows at the start: their Bond is the only one in all of Auren that has not faded. It burns darker with every passing day.

Naia has known Daven's name since she was seventeen. He has never once looked at his own.

Forced into proximity by imperial order and a crisis neither can solve alone, the two move from friction to reluctant partnership to something neither has language for. But when Naia uncovers historical evidence of Registry manipulation and chooses to believe the worst rather than face what she feels, the fragile thing they have built fractures, and both must decide what they are willing to fight for when the data runs out.

Written in Starlight is a romantasy about two people who built their lives around certainty, and what happens when the one thing they cannot explain turns out to be the only thing that matters.
