General Park-head of Sky Corps Academy-must assemble a team of heroes to protect humankind from alien invasions, and Stanford Yu, Maya Sanchez, Frank Olivetti, and Park\'s own daughter Olivia may have been pulled into the role by fate... as they are Earth\'s best hope. But there is more to their relationships with the symbiotic, sentient giant Robos they pilot... and the alien threat of The Sharg is far more epic and widespread than any could imagine!
