Mark of a Prime

She was just a normal, human girl until one day giant robot aliens with red optics attacked her home looking for her. The Decepticons wanted her, but for what reason?

The Autobots saved her in time, and they find out she is the key to an important prophecy spoken by a Cybertronian prophet after coming home. After Optimus Prime had died.

Just how important is this girl, that Starscream and the last of the Decepticons still out there want her dead or alive? What power could this one small, human girl hold inside her?
