About The Book

Lythlet and her only friend Desil are shackled to a life of debt and poverty that she fears they will never escape. Desperate for money, they sign up as conquessors: arena combatants who fight sun-cursed beasts in the seedy underworld of the city.

Match-master Dothilos is initially enamored of Desil’s brawling reputation, but after seeing Lythlet lead the pair to triumph with her quick cunning, he takes her under his wing, scorning Desil. Ambition takes root in Lythlet’s heart as a life of fame and wealth unfolds in her imagination.

But Lythlet isn’t the only one out for coin and glory, and she soon finds herself playing an entirely different game—a game of politics and deception. As the cost of her ambition grows, she will have to decide if sacrificing her honor, and only friendship, is worth the chance to shape her own fortune.
