Chapter 1

Three months after her seventh birthday, only child Catalina "Kitty" Sterling and her parents Solstice and Amethyst stumble across a battle between the Auto Bot leader Optimus Prime and the Con warlord Mega Tron during a morning walk in Chicago, Illinois. During this, Amethyst and Solstice use their bodies to shield her from the hit from him and are fatally wounded. In their final moments, they sacrifice themselves to allow Optimus to force the warlord to retreat and safely escape with Kitty, whom he later partners with Auto Bot soldier Cliff Jumper. To honor their sacrifice, Optimus and his teammates retrieve Solstice and Amethyst's lifeless bodies from a hospital and lay them to rest in two sandy graves outside their base that evening. Ten years later, Kitty, now seventeen, and Cliff Jumper, who is now her guardian and combat partner, battle several Con soldiers at a energy mine in the countryside and finish the soldiers off with the help of their friends.
