The Combat Codes — Alexander Darwin

The Hunger Games meets Ender's Game, infused with a healthy dose of mixed martial arts action.
In a world where single combat determines the fate of nations, the Grievar fight so that the rest can remain at peace.
Cego is a mysterious Grievar boy forced to fight his way out of the slave Circles into the world's most prestigious combat school.
At the Lyceum, Cego will learn a variety of martial arts from eclectic teachers, develop deep bonds of friendship and fight against contentious rivals to climb the school's rankings.
But, Cego will find far more than combat studies at the Lyceum. He will find the mystery of his past unraveled by forces greater than he could ever imagine.
