“This is the Arena, and here we live to die.” This is the motto of genetically-altered gladiators, the winged humans called Galdoni. Kale, nursed back from the brink of death by students, is given the chance to experience life as a human. When he is captured, he has to use what he learned in the world outside the Academy in order to free the other Galdoni and return to the human girl he loves.
