I do not own Harry potter only my oc

It was a cold October the leaves were turning orange and beginning to fall off the leaves seeing as it was hallowen the Potter house was covered in decorations the window had fake cobwebs hanging from the corners and a skeleton sat on the grass in the garden. Inside the Potter household was Lily Potter and James Potter with their beloved son Harry potter. Lilly and James best friends, Sirius and Cassidy Black, had decided to see them on this day with their 15 month old daughter Kerenza. Kerenzawas born on July 29th and had her father's black hair and her mother's chocolate brown eyes. Both the Potters and the Blacks knew that meeting when th Potter's were in hiding was dangerous but they risked it anyway. As the clock struck ten o'clock a clocked figure walked to the door and clicked the lock open inside the men looked quickly outside to see a frighteningly recognizable face. Sirius and James grabbed their wands and ushered the women to take the children upstairs Cassidy looked back to Sirius saying sadly as she held Kerenza to her.

"I love you Sirius" his eyes were full or worry and dread but he managed to smile and say.

"I love you to" he wiped his forming tears and pointed upstairs. "Go quickly upstairs we'll try and slow him down" as the door opened the two men were not ready for the power this person possessed.

"Avada Kedavra" a green shot hit James making him fall to the ground lifelessly. Sirius screamed for his best friend to awake but he knew he would never be able to awake. Sirius tried to fire at the hated man but a spell hit him. "Stupefy" A redy Orange colour hit Sirius making him fall unconscious. The cloaked man walked up the stairs where the two women were hiding he quickly killed the women and he then turned to the children he roughly grabbed Kerenza's arm and pointed his wand on top. "Morsmorde" the image of a black skull and snake appeared on the child's arm making her scream in pain. "I'll be back for you" he hissed to the girl he then turned to Harry pointing his wand at him he casted. "Avada Kerdavra" in a blinding white light the spell was cast but Harry remained unscathed, well apart from a scar on his forehead. Later the ministry of magic came to the crime scene where Sirius was arrested for murder and Harry and Kerenza where found. The two children where kept together and sent to Harry's uncle and aunts house they were called the Dursleys and that was just the beginning of this horrible turn if events.
