Well this is my frist attempt at a FF, so dont hate me if it sux.

"All mortals BEWARE" said Harry, as he wiped the dust off the ancient tome. As the writing seemed to shimmer and disappear only to reappear and fizzle as if etched with acid.

"Harry don't touch it, I've heard about those kinds of books, squeeled Hermione, the pages hold powerful, long forgotten magics which have been known to cause the owners to vanish." Hermione clearly agitated gave Ron a death stare as he egged on Harry.

"Come on Harry, Sirius wouldn't have mentioned it if he thought it would be dangerous for US" pleaded Ron.
"Besides, think of how fun it will be to pay back Malfoy or even Snape!"

"Yeah, Ron's right Hemione, don't tell me you wouldn't mind a little pay back after Snape made you drink Nevile's potion for correcting his pronunciation.
The way your hair turned into octopus tenticles, that was pretty embaressing, not to mention when Malfoy shot you with that spell to make you say, 'Either I'm having a REALLY bad hair day or someone spiked the pumpkin juice'" said harry.

Hermione said nothing and silently fumed, but admitted to herself that they had a point.
Later on, the three of them flipping through the book come across a page which unlike the other pages had writing which someone recognised.

"Are you lot up to mischeif again?" said an resonate voice. "Hello Harry".
"Hello Myrtle" said harry.
Ron sniggered under his breath, and Hermione give a sigh.
"Why dont you come to visit me anymore? I would think after all the help I've given you, you might feel obliged to come see me more often.
But I havent been all alone, I've got someone I'd like you to meet. Harry this is Anita, she drowned in the lake and we just now bumped into each other."
"Hi, H-Harry." anita said blushing
"Um yeah, hi."said harry reluctently as Ron bursts into giggles and Hermione elbows him.

Hermione all of a sudden short tempered, snaps "Look Myrtle we're busy, could you and your friend find something else to do."
Myrtle puffs up going blue and screams, "Why should I leave, I was the one who died in here."
Before Myrtle could continue her tirade Harry cuts her off. "Myrtle, Hermione didn't mean to be rude but we are kind of busy. Now you have a friend, maybe you two could go do something."

She softens, "Well maybe we could go see if any of the other male prefects are washing. You remember Harry when we were in the prefects bathroom together, don't you?" blushing profusly.

Ron practicaly exploded with laughter, and Hermione spluttered indignantly, "You whaaaattttttt?! You and her were in the bath together!!"
"It was not like that." proclaimed harry
Myrtle grinned in satisfaction at hermione's outburst, then Anita glancing at the book recognised some of the runes on the page.
"Hey, I know those. It says
'All mortals beware,
those who wish thy will, be done
must first ask what web will be spun,
for each action taken a recourse has begun,
eye's that cannot see will be needed by three's,
root one to the spot of wormwood and rot.....'

"Of course, Aramaic Runes, why didn't I see it before!" said hermione recovering her composure. "And these are the ingredience we'll need."
Snatching the book off harry she read more mumbling to herself.

Harry and ron exchanged looks of confusion then shrugged. Mean-while myrtle and anita were whispering to each other, let out a few giggles, pronounced they were off to make their own fun and left.
