Summary:
Stella loses her brother and is on a quest for revenge. She doesn't know how far she is willing to go (the story is mainly an internal conflict) and she doesn't know if she can ever care about someone again. Her brother's death may have turned her into something terrible and unrecognizable.

Personal Opinion:
I really love the covers you asked me to make. My personal favorite would be the one with the lips. Your story @theanimal240 is really valuable to me, because you can feel her pain. I'm really intrigued by Stella, as well as her powers.
