Elizabeth Witwicky, the niece of Ron and Judy Witwicky and the cousin of Sam, finds herself rescuing an Autobot on a whim and joins the adventures of war between the Cybertronian factions Autobots and Decepticons. Growing up outside of Mission City in the Valley of Fire, NV., Elizabeth's father taught her how to fix all kinds of cars and build her own weapons. Her father disappeared when she was eighteen, and in turn handed down his auto-repair shop to her. While in Mission City to pickup some equipment, she finds herself in the middle of the battle to claim the Allspark where she rescues an Autobot and fixes him up. Where will this new friendship lead? What twist of fate awaits her?
