For centuries, the world has feared two things:
the Sun-King of Noctisolar, and the assassin who walks like moonlight.
Seryn was raised blade-first, tempered by mercenaries and forged beneath the cold eye of Vaelorin-the Queen Assassin herself. With a shadow-beast at her side and starlight beneath her skin, she has become a whispered myth. A ghost. A weapon.
Never a woman allowed to love.
Never someone meant to be saved.
Zehran inherited a kingdom carved from war and ruin. Crowned young, blood on his hands, he has ruled with fire in his veins and a dragon at his command-loyal only to him. He expected rebellion. Betrayal. Assassins in the dark.
He did not expect her.
When Seryn and her bonded sister Aelira perform an ancient ritual of constellations and starlight, decades pass like seasons. Their bodies remain young. Their names vanish into legend. Until a contract finds Seryn's hand-one worth more than any she's taken.
Kill King Zehran.
But instead of a blade to his throat, Seryn finds war on the horizon, traitors in the court, and a king who defends her with fire strong enough to burn kingdoms. Forced into an uneasy alliance, sun and moon stand side by side-equal, dangerous, inevitable.
Their trust is fragile.
Their desire is forbidden.
And every moment without a kiss feels like a war they're losing.
As armies march and starfire stirs beneath Aelira's skin, Seryn and Zehran must confront ancient magic and the truth neither of them can outrun:
**The world will bow to them-or break beneath them.
Because even fate cannot separate the Sun-King and his Crownless Moon.
