A/N: I don't own anything except for Celeste!

Diagon Alley

"Hurry up, Celeste! We're leaving soon!" My sister, Veronica yelled. Veronica was in her last year at Hogwarts and I was in my fifth year. Veronica was head girl this year and one of the prettiest girls in her year. Veronica had shoulder length curly hair that was a deep brown, like the colour of her eyes. Veronica was a nice tanned colour and her body was curvy in all the right places. Sometimes I wished that Veronica wasn't so great, because everyone is always disappointed when they see me. They aren't that disappointed when they SEE me, it's only when they realise how different I am from my sister. I have straight brown/red hair that goes down to my ribs, hazel coloured eyes, and a tanned complexion. I was popular in my year, but I didn't like it. My friends always backstabbed me and I even caught Jennie making out with Brett, my boyfriend. I didn't really care though; I don't like either one of them. I did have a close friend who I knew would never backstab me, Lily Evans. Lily was my best friend and she was really nice. I told Lily everything, even about my crush. But more on that later, on with the story.

I grabbed my money and then raced down the stairs to the dining room. Veronica sighed,

"Why do you always take so long? Thinking about your life in Gryffindor?" Veronica sneered. You see Veronica wasn't like me. Veronica was in Slytherin, and so was my Dad. My Mum wasn't though, so she didn't mind me being in Gryffindor, like the others. At least I had some support in the house. How her and Dad got together, I do not know! I grabbed some floo powder and threw it into the fire before saying, 'Diagon Alley' I quickly made room for Veronica to come through.

"Now I am going to go to my decent friends, while you go off to your lame friends" Veronica said going over to her Slytherin friends. I looked around and then at the clock. I was supposed to be meeting Lily at Flourish and Blotts in ten minutes, so I made my way over there. I pulled out my book list and started to look around for my books. Once I had all five of them, I turned around and smacked into someone. The books dropped onto the floor.

"Oh I'm so sorry" I apologised, feeling my cheeks burn as I started to gather them up.

"No it's my fault," Said a voice that I had grown to love. I looked up and there he was.

"Already running down girls, Sirius! How rude!" James Potter said laughing.

"Be quiet, prongs! So sorry about that. Here," He handed me back my last book and then grinned.

"Hey you're that girl, Celeste! Most talked about girl amongst our boys. You and that Lily Evans" I blushed, I wondered if Sirius talked about me. I was saved from having to stutter a response when Lily came walking over,

"Hey Celeste! Sirius what are you doing here? And you James" Lily said a little coolly. I think Lily thought that James was a bit of a prat.

"Well you see my friend, Sirius, here decided to run over your friend for her attention."

"Like he needed to do that" Lily replied, grinning. I elbowed her in the ribs.

"And what does that mean?" Sirius asked, a twinkle in his eye.

"That I've got a boyfriend that I'm going to meet any minute now. Have a great day, see you!" I said, taking Lily's arm and going to the front of the shop to pay for the books.

A/N: I know it's short, but it's the starting and this is my first marauders fic so bear with me and PLEASE review! And in the next chapter there is going to be a lot of drama, so sorry about that coming in so quickly but I needed to do something.
