This is a fanfiction based on the Harry Potter Series characters, I would love feedback, anything, but give reason, please DON'T just say stuff like "I hate this fic!" and not give a reason. I will be posting my chapters later on, when I finish them.
Now the story...it's short:

Well now, how did that happen? She thought, sadly examinating her scar. There was a very deep scar running up her arm, gushing blood. Holly rushed to the Hospital Wing, when she got there Madam Pomfrey was tending to other student, on the side table there was a bottle of Skele-Gro. "Dear! What happened to your arm?" she hurried over to exam it. "How did this happen?" Holly was starting to feel dizzy and nearly fell over, "I don't know, it was just there." Madam Pomfrey hurried to get wrapping for it, Holly was just watching her bustle off, and then blackness as her head hit the pillow.

Rosie was glad she had been sorted into Ravenclaw, now she knew she had her mother's brains. She was walking down the hall trying to find a bathroom, this place was huge. As she walked up the steps a girl ran past her, the girl had a bandage on her arm, and tears in her eyes. The girl, fiery red hair flying out behind her, ran down the stairs, Rosie followed her, as quickly as she could. The girl lead her to the entrance hall, the doors where wide open, it was a beautiful day. The girl tripped at before the doors, but did not go any further.

"What's wrong?" Rosie asked, slowly approaching the door. The girl looked up quickly, she had shocking white eyes. It was Holly, a girl from her house, though two years older.

"What do you want from me?" she screamed in terror, and once again started running. Rosie followed only so far, she stopped trying after awhile, but she could see that Holly had ran into the Forest, she had to tell someone. Rosie started running back to the castle as fast as she could. She got to the entrance hall, running close to the wall, someone jumped out of one of the empty classrooms and grabbed her covering her mouth. The person shut the door and whispered, "Trust me." The person let go of her and she looked to see who it was, it was a boy, at least a fifth year.

"I am sorry I had to do that,” he said sitting down, "My name is JaKota."

"Why did you do that?” Rosie demanded, as she too sat down.

"Holly just needs sometime to cool off, trust me, I know what she is going through." He sounded so sure of himself.

"She cools off hanging out in the Forbidden Forest?" Rosie once again demanded, amazed at how he could be so laid back at the moment.

"Yes, in fact she does." He said leaning back. "Almost all my friends do, when something is bothering you, find something else to focus on. So scared you can't think straight. We don't worry that much about being in any real danger, but it is nice an' quiet."

"Whatever, you sure she will be okay?" asked Rosie getting up.

"Yup, she's gone in there before, no need worrying about her, she's strong."

"Fine" said Rosie and left.

i dont understand the time line but its mysterious and created suspense... i like it!!! :D

I don't really understand this....I mean does it take place while Harry is there or while his children are there?Could you explain the characters a bit more also?

Its a little confusing as to when your story is taking place. My assumption is that is after the trio have gone through. I like it though. Short, sweet, to the point, and adds a sense of suspense
My only complaint is that its a little bare of details. But I just really like being able to picture exactly what things look like, so I might be a little biased.

Hm, like everyone else said, this was a little bit confusing. It is good, no doubt, but I have no idea when this is happening. The only thing I can make out is that Holly is somewhat like Lupin. But I guess that's just me. *shrugs*

It was a bit confusing, yes. I'm not exactly sure what is happening, but that may be because you made it sound like that for suspense, like the others are saying. When is this happening? After the others graduated, or are they to come in later in the story?
