Chapter 1

2 years later

"Goodbye Mrs. Barnabe! I see my friends now." Serena waved goodbye to her caretaker, finally glad to be rid of her, and pushed her cart towards her friends. Everyone had changed over the summer, including her. Her hair was wavy now, and almost reached her waist. Her breasts had also gotten bigger, which she was thankful for.

"Serena!" Hermione was the first to see her, she rushed over and hugged her. Hermione's hair was pulled back into a tight bun, she had grown taller, but not as much as Ron and Harry.

Serena hugged Harry and Ron, "It's so good to see you all. I swear I never thought I'd be glad for school to start."

Ron frowned, "I don't think I'll ever be glad for school to start."

Harry smiled and patted Ron on the back, "Oh come on. We're third years now. We can sit back and enjoy what ever comes our way."

Hermione shook her head , "I don't think so, we'll have much more homework this year, and if you think I'm going to let copy my work you are poorly mistaken."

Mrs. Weasley came rushing over, "Oh Serena, you're here now." She pulled her into a quick hug, "We need to be going, the train is boarding now. Come along."

They all lined up to go onto the platform, Percy and Ginny went first, followed by George and Fred. Then Hermione and Serena went, but before Harry and Ron went, Mr. Weasley pulled Harry aside, "Remember what we talked about, stay out of trouble." Harry nodded and Ron looked at him confusedly before they went onto the platform.

"Harry, Ron! Over here!" Serena was calling them from a few doors down the train. They moved their carts and started to unload their trunks onto the train. Once that was done they got on and searched of a compartment. They at last found one, but it held a very grungy man sleeping by the window.

"It will have to do, all the others are full." Hermione sat down across from the man and Serena sat down next to him. Harry sat next to her and Ron sat next to Hermione, just before they closed the door an orange and white cat ran in and hopped on Serena's lap.

"Oh, Frasier, I knew you'd make it in time." Serena pet the cat as it curled up in her lap. "So how did your summers go?"

"Oh not much happened, except I blew up my Aunt and ran out of the house where I got picked up by the night bus."

"What?" The other three said together.

"I'll explain later, it's not that important. But, there is something that is." The three waited expectantly, "You know Sirius Black?"

Serena stiffened, but no one seemed to notice. Hermione ever so thoughtfully, "He's the one that escaped from Azkaban."

"Yes," Harry continued, "That is what Ron's dad was talking to me about. Apparently, he escaped so he could come after me. And if he finds me, he's going to kill me."

"Harry," Hermione said, "do you know how serious this is?"

"Well it can't be all that bad." Ron said.

"What?" Hermione glared at him.

"What? We'll be at Hogwarts. Harry will be safe there. And we have Dumbledore."

"Are you sure he's trying to kill you?" The three looked at Serena who had finally spoken.

"Who else would he try to kill? He was Voldemort's man."

"May be people got it wrong. May be it was just some big mistake."

"Serena, you can't be serious." Hermione looked at her. Before Serena could answer the train lurched to a stop.

"Why did we stop?" Ron asked. He got up and looked out the door.

"I don't know." Hermione looked out the window, "We can't be there yet." She gasped and backed away from the window that was now frozen over with ice. Frasier got up and hissed at the door and ran underneath the bench. Serena got down on the floor and whispered to him, "Come on, it's alright. Come out kitty…"

The four of them stopped and looked at the door. Serena had a prickling sensation on the back of neck and everyone seemed to be frozen to their seats. Outside the door a black shape came into view. The door slid open and a hooded figure looked around the compartment, it stopped at Serena who was sitting on the floor.

It let out a strange noise and moved towards her. She felt cold, and an overwhelming sadness seemed to strangle her. She couldn't breathe and collapsed on the floor. The man that had been sleeping in the corner leapt up and pointed his wand at the thing and a bright light flew from his wand. The thing shrieked and left the compartment. Serena was lying on the floor, motionless.

Hermione was on the floor beside Serena trying to shake her awake, "Serena?" The man moved Hermione aside and passed something under her nose. Serena gasped and sat up. She was shaking visibly and the man gave her his coat.

Hermione moved Serena to a seat and put her arm around her, "Will you be okay?" Serena nodded and the man handed each of them a piece of chocolate.

"Eat the chocolate. You'll feel better, now I'll be back in a moment, I have to talk to the conductor."

"Wait, Professor Lupin," he turned around, "what was that thing?"

"A dementor, now if you'll excuse me." He left the compartment and Ron turned to Serena, "How did you know who he was?"

"Well, one, it's on his briefcase. And two, he lives across the street from me, he…he was an old friend of my dads." The train started to move again and the four ate their chocolate in silence.
