In one day, the world is stunned as the enemy is driven back, and Sky is left with the death of his mother and the disappearance of his father. As the years pass, he meets Chelsea Alawi, a royal slave, and with her help, he begins to heal. However, as Sky comes to terms with the tragedy, he learns that his father still lives, and pirates want him dead or alive. With new purpose, Sky must assemble an airship crew and prevent a ruthless pirate lord from coming to power, or else the world faces all-out war.
