Game On.

Not a good idea

Harry and Luke were rifling through the old, leather bound book, laughing as they read the spells and made jokes. Cat was loudly stating how not good this idea was, whilst trying to persuade Pete to come out from under the desk, where he'd taken shelter the moment he'd been released. He was now sitting under there, giggling and playing with Cats phone which he'd managed to take.
Cat groaned loudly as she squatted on the floor, trying to reach Pete under the desk.
"Boys, I really don't think it's a good idea to play around with mums stuff. We're not even supposed to be in here, who knows how much trouble we'll be in if she finds out!...aaaargh! Come here you Little thief! Gimme my phone back!"
"No." Stated Pete, smiling evilly. "I think I'm gonna change all your contact names into super heroes!"
Cat gave out a growl and launched herself partly under the desk, swiping at him like, well, a cat.
Luke looked up from the book to stare at his stepsister scrabbling under the desk. He rolled his eyes. "Yeah, and that's not gonna end badly."
A loud thud punctuated his words and a moment later Cat drew back, rubbing her throbbing skull. "Aaaargh!" She cried in frustration " You better not muck up my phone, you monster!"
Harry laughed, glancing up for a second.
"It's not funny!" Cat practically screamed.
"Selfie!" Chimed Pete, followed by a camera flash from under the desk. Cat had to try very hard not to throw something at him.

"Hey, look at this!" Said Harry. "Its some kind of summoning spell. We should totally try this!"
"We should totally not try this!" Said Cat, frustrated that no one was listening to her. "We should totally leave now so that mum doesn't find out and kill us!"
"She's gonna kill us for the party anyway." Added Luke, shrugging nonchalantly. "At least this looks interesting. It's like having a seance."
"And having a seance is on your to-do list, is it?"
"At least its more interesting than the party."
Cat couldn't fault his logic. "Fine, but Pete goes back to bed first."
Harry smirked. "We could always use him as a human sacrifice."
Cat gave him the death glare.
"Kidding." He said, shrinking away from her gaze.

Cat rolled her eyes and followed the others out of the room.
"This is not a good idea" she mumbled.
