Prologue

Lily and James Potter had just sat down in the study with their neighbors, the Parkers, when the doorbell rang. James knew who it was and knew that there was no way for them to all escape now.
"Lily, Maria, take Harry and Anna and get out of here. GO! NOW!"
Lily and Maria ran to the back bedroom with the two babies while James and Jonathon tried to head of their assailant. They heard James open the door.
"Where is the child," said a snake-like voice calmly.
"You'll never have her," yelled Jonathon.
"We shall see about that. AVADA KEDAVRA!" yelled the man.
A body sank limp to the floor.
"Jonathon," breathed Maria, tears already flowing from her eyes. She looked out of the cracked door and could see her husbands lifeless body. His eyes were still open.
"Now, James. I'm sure you don't want the same to happen to you. Where is the child?"
"She's not here..."
"LIAR! Give me the girl and you may live!" screamed the man in a hissing voice.
"I'd rather die," spat James.
"As you wish," the man said, even more calmly than before. "Avada Kedavra!"
Lily saw the green flash and watched as her husband sank to his knees and toppled forward.
"NO!" she screamed, unable to suppress it.
Slowly the man walked toward the door.
"Lily. Run. Take them both. I'll keep him here long enough for Sirius to arrive," Maria said handing her baby to her best friend and kissing the three of them on the forehead.
"I'm not leaving you," said Lily in a shaky voice.
"Aha!" yelled the man as he threw open the bedroom door. "Trapped like rats..."
"Leave Voldemort!" said Maria fiercely.
Voldemort aimed his wand at the now wide-awake Anna. There was nothing they could do now. "AVADA KEDAVRA!" he screamed. A flash of green light erupted from his wand tip. It hit Anna squarely in the chest tearing a big, gaping hole right over her heart. Beams of green light ricocheted off of her and hit everyone in the room. Two huge beams hit Maria and Lily and they died instantly. The small beam that hit Harry left a small, lightening-bolt shaped cut on his forehead. Voldemort seemed to explode amongst the beams. The foundation of the Potter house began to crumble and all that was left was the back bedroom, bodies, and debris.
Even though Anna had been hit at point-blank range with the Avada Kedavra and had a gaping hole in her chest she was still alive. She and Harry screamed at the tops of their lungs for what must have been hours before someone found them.
Harry was sent to live with his aunt, uncle, and their child. The Dursley's were a nasty bunch, but atleast they were related to him. Anna had no one.
She, like Harry, was sent to live amongst muggles to live out a "normal" childhood. But unlike Harry, she would not return to the wizarding world. Or would she.
