Mia is finally ordained to the blade, but not everyone in the Crimson Church thinks she deserves it. Even the murderers of her family almost do not appear in public, so the chances of revenge are less and less. To kill the highest dignitaries of the Republic, Mia is sold to the Gladiator college for a chance to finish them off. In the sands of the arena, Mia finds new allies, fierce rivals, and many questions about her strange attachment to shadows. But as conspiracies unfold within the walls of the college and the death toll rises, Mia will be forced to choose between loyalty and revenge, as well as uncover a secret that could change her view of the world.
