Prologue.
Adam and Rose Potter were forbidden to marry, so they left the wizarding world and got married none the less. A year later Rose died giving birth to Hailey Rose Potter. Adam loved her with all his heart and did all he could for her to have a good childhood. He wrote down his will as soon as Rose died, for he knew that with Voldemort around one could never live all his life in peace. So he wanted to make sure that his girl would have all she needed. Adam packed two trunks with things she would need – books on the wizarding world and it's customs, her family tapestry, which updated itself constantly, a port key to the Potter manor, a note with an activation password, a letter from himself explaining how she was magical, well actually it was only a piece of paper with spell on it. As soon as the correct person opened it, a ghostly figure of Adam Potter would appear and explain everything up until his own death. There was also a copy of his will, so that his daughter would know exactly what she owned, plus a simple guide of Diagon Alley and how to get there, some wizarding money, in case she actually got stuck at the Dursleys, a copy of the Marauder's map, which was signed 'A guide of Hogwarts for my beloved daughter' and some simple spell books. Adam charmed the trunk so that it showed to anyone, except Hailey, that there were only clothes and a few muggle pictures of Adam, Rose and little Hailey.
Adam was one of the most active members of the order of phoenix and Voldemort tried to lure him in, or kill him on countless occasions. So after the prophecy was made Adam thought that they were safe, after all Hailey was born on July 31st at 11:59 and by that time she was already 6 years old, but Voldemort thought otherwise. He first went after Hailey, but failed. He tried to talk Adam into giving him the child, but didn't succeed. He killed him, but not before Adam sent a distress signal to the Order. Voldemort cast the Avada Kedavra on Hailey, it rebounded, but missed its castor by mere inches. The curse left a scar on the girl's neck, but she had long hair so no one noticed it. When Voldemort tried to cast the spell once more, the Order arrived and he left, heading to Godric's Hollow to try and kill the rest of Potters.
That Halloween four children lost their parents. They were – Chris & Harry Potter, Hailey Potter and Neville Longbottom. Young Chris Potter with his strange lightning bolt scar on the forehead became the 'boy-who-lived', while Harry Potter was asleep all the time in his own room, where Lily Potter forgot him. The Potter twins and cousin were sent to their aunt and uncle, the Dursleys, while Neville was brought up by his grandmother, Augusta Longbottom.
