In Rydor, royals rule monsters with artifacts and their people with fear. The poor pay for protection, but the ones higher on the pedestal are the true predators. Those not born with titles can only hope that criminals like the Phantom Thieves might save them in their moments of need. No one knows the names or faces of the thieves, but they do know how much the royals despise the monster hunters. When Calderi guards finally capture one of the thieves, the other will prove again nothing will stop her from finding him and that she will grant no mercy to any that stand in her way.

While Calderi plans the fate of their prisoner, a lady arrives at court to await a marriage to the infamous prince. She has trained for this role all her life, but no one prepared her for how cruel this family could be. When stripped of all she loves in the vilest manner, the beautiful flower decides to grow thorns and dares to learn banned magic in pursuit of defeating the court.

But there is more than one game being played. All games weave together as five paths collide. Everyone is a pawn with their own dark secrets, and no one can win without sacrifice. Soon all will see that monsters are not the only beasts willing to devour their prey.
