Lily and Arabella's Hogwarts Life, Chapter 9: Summer and a Complete Transformation

The rest of the school time was only fun. Lily was a bit sad about leaving, but she reminded herself that she would be back the 1st of September. She hugged Remus and Peter goodbye, and herself, Arabella, Iris, James and Sirius dragged their luggage into a huge limousine. Jacob stopped to let Bella, James and Sirius off at their houses before driving up to the Evans Mansion. Daisy came running out and threw her arms around Iris. After that she jumped at Lily who lifted up the little eleven-year-old and carried her into the house.

Iris took her sister from Lily's arms and hoisted her piggyback onto her own back. The three of them followed the delicious smell of food to the kitchen where Alice was to be found in front of the stove.
"Mmm, smells delicious. What is it?" Lily asked Alice while she grabbed a pitcher of Pumpkin juice from the fridge, her mother had fallen in love with the product from first taste and now it was always to be found in the Evans houses.
"Chicken wok." Alice said simply. "It'll be ready in ten. Get your parents." Lily nodded and ran off with a glass of cool pumpkin juice in her hand.
"Mom! Dad! Dinner!" She almost crashed right into her mother. Her mother laughed and grabbed the glass of juice.
"Thank you darling."
"Hey! That was my juice!" Rose took a sip of the juice, pointedly ignoring her daughter.
"Argh. You're impossible!" Lily screeched and stomped into the kitchen again.

The days and weeks flew by in the Evans mansion, along with the usual visits from Arabella, the Marauders and other schoolmates. Daisy had taken over Sandra, Lily's one year old Rotweiler, and they could almost always be found together. In the end of July Daisy received a letter by owl that told her that she had been accepted to Hogwarts. The next day she went shopping with Iris and Lily in Diagon Alley.

Daisy was exited about this New World, and terribly grateful for having a gang of people to introduce her. The summer passes quickly, almost too quickly, and soon they found themselves tossed into the world of Hogwarts again. The lessons and teaching passed in most usual manner, and soon the first full moon of the school year approached. And this would be the day of Sirius, James, Peter and Iris's final transformation. They snook out after Madam Pomfrey had re-entered her hospital wing and carefully glided towards the whomping willow. Lily enlarged her wand and carefully prodded the knot on the tree, freezing it. One by one they tiptoed into the secret entrance. After a minute or two they approached the solid door leading into the shrieking shack. There Remus met them, pale in the face and eyes spilled. He lead them into the bedroom of the shack and they all dumped down on the bed.
"Well," Lily said. "Now I want you four to transform. Sirius, you go first." Sirius nodded grimly and hoisted himself up. Standing firmly on the floor he closed his eyes in concentration and popped into a huge, shaggy grim-like dog. As the familiar Sirius appeared again he grinned like the Chesire Cat and demanded to know what he had become. After a five minutes had passer, a tiny, brown rat appeared in Peter's place and a minute later a stag had taken the place of James. Then Iris lifted herself up and became the centre of everyone's attention. She breathed deep and popped into a wonderful Arabian horse. Chestnut coloured like her own hair. When she popped back into herself Remus grinned at his six friends, even though it didn't quite reach his eyes. Lily popped into a tiger and the others to their respective animals. Remus sent Lily a mysterious stare before his entire body shook. It all passed like all the times before, but Lily and Arabella both noted the widened eyes of their friends.
