"Avada Kedavra!" The shrill voice of Voldermort called. The spell that struck at one of the kids rebounded. The room blew apart. Harry Potter was makers by his scar. But the little metamorphagus was caught by all of the magic rebound.
She cried in pain of so much of it. But the world decided to send her to the family she should have had. Or what it could do. She was sent on the Potters door step. The same Potters that we're raisi young James Potter.

"Oh!" The voice of Eve Potter called as she say a sleeping girl laying on her doorstep. "Frank!" She called to her husband.
"Merlin!" He said as he laid eyes on the girl. "Is that Dora?"
"No, she is to young." Eve replied as she leaned down and picked her up. "All her blanket says is Hera."
"I'll go Floo the Ministry. See if there are any that match her." Frank said worried crinkles on his face."
"I gues I can let her play with James." Eve said equally worried. "She looks in good health. But the magic around her is, strong."
"Yes. That is what worries me."
"Me too Frank, me too." She said sighing as she cradled the girl.
As Hera started playing with James happily, Frank went to the Ministry of Magic (MoM) to see if there was even a recorded birth of this mystery girl named Hera.

After three days of Floo calls, looking through files, and asking Healers, there was no luck.
"We have registered the girl as an unknown orphan taken under your care names Hera Zamara Potter. Yes Lord, Lady Potter?"
"Yes." Eve said. "She was laid on our door because of Fate. Somethings are just supposed to me."
"Lord?"
"I fully agree. And I believe our son James does to." Frank smiled.
"Good. Will you be blood adopting this child?" The official asked.
"No." Eve said, "I am not the most fond with this type of adoption."
"Okay." The official said. "Each of you sigh with a drop of blood here." He said as he gave each of the a needle.
They both pricked their fingers and let a drop of blood spill.
"Thank you." Eve nodded to the official. He bowed in return.
The couple walked through the fireplace back to their house and saw their children playing happily. "I think this was a good choice." Eve said to her husband."
"Yes, even Potter boys need a girl for them to be yelled at by."
The both laughed and watched their son and newly deemed daughter play happily.
