A Star's Return

All Shena Coulson and Jessica Overs ever wished for was to be taken away from the place they called home. Little did they know was that someone finally heard their pleas.
...........
Shena Coulson was the only daughter of a single mother. One whom she loved with all her heart. Only to have her ripped from her by the jaws of death. Alone and broken she's sent to a foster home where she meets another girl not unlike her.
..........
Jessica Overs was born without the gift of sight. Upon seeing this she was abandoned on the doorstep of a orphanage. Raised in a home full of other children who see her as nothing more than a breathing punching-bag. Jessica believed that she would be alone for the rest of her awful existence. And then she met Shena.
........
If there was one thing that these girls loved more than each other, it would have to be Transformers. Both found themselves entranced with the idea of aliens who could take the shape of automobiles. Even more, the thought of being needed.
Shena did everything she could to protect her bullied friend, but somehow Jessica still was harmed. After she found her blind friend passed out in the living room with a bleeding head, she'd finally had enough. With her unconscious friend Shena fled that hell hole.
But on the way out, she was shot down by their foster family, who feared that Shena would turn them into the authorities. Wounded and dying, Shena made one last cry. One that was filled with so much pain, it echoed out into the far reaches of the universe.
With Jessica's hand clasped in hers, Shena watched as a single star twinkled and then went out. Her breath leaving her.
............
Instead of finding themselves at the pearly gates, the duo are sent to a place where more heroes are needed. One that these girls aren't all to new to.
There is nothing more confusing than waking up to the sounds of screams. Even more the sight of two of your favorite characters duking it out.

Stars have to fall to make wishes...
