I don't own the pictures nor the Ones in the cover and Since Danny and Grace are twins the only thing different they have is that Grace has paler skin and longer hair. Okay, let's start.

My name is Danny Fenton. My best friends Sam and Tucker persuaded me to let them see my parents lab and I reluctantly agreed, my sister Grace decided to come along since she always liked the paranormal stuff but not like hunting ghost (as my parents)more like just seeing them. Sam said that we should enter the portal to ghost zone since it was turned off and it didn't work, I wanted to enter but wasn't sure it be safe, that's when Grace offers to go...

Danny's POV
"Hey, I'll go." Said Grace carelessly
"No!, haven't you heard what I just said!" I yelled worriedly
"Yeah you said 'don't know guys could be dangerous'"
"So... why the hades do you want to go slinthead"
"Hey! Slim it shank! Don't use my spells against me Potter!" she yells back meanwhile tucker and same were looking between us dumbfounded.
"What the heck are you guys saying!" Sam said angrily
Grace smile apologetically "sorry fandoms, um... have you read/seen Percy Jackson (hope only read it, horrible movie) The Maze runners or Harry Potter?" She asked
"No."Sam and Tucker say in sync.
"Oh..." say Grace a bit offended and to be honest I was as well. "So... there's no point in trying to explain any way..." she said as she takes a step forward to enter the closed portal.
"Wait!" I said as I grab her wrist.
"What!... wait this means my little brother actually care?" She said with a risen eyebrow. I let go of her wrist.
"Obviously I care! Besides, I'm the big brother" I said
she sighs "for ten minutes anyway"
"Just be careful okay."
"Alright" with that she enters.

Grace's POV
"Woah" it's the only thing that I could say. "It's way... more impressive in here"
I start passing my hand through the walls. But I got distracted and press a green button by accident. The machine starts to grumble.
"Grace!" I heard Danny scream before running towards me entering the portal. Suddenly something super weird happens, it passes through my body something like lightning it hurts... then I passed out, well sort of Just for a brief moment maybe just some second, Because when I woke up I was falling and Danny or at list I think it was Danny rush forward and catch me.
"D...Danny? Is it you" I said my voice quivering, my head dizzy.

Danny's POV
"Y...yeah? Are-are you alright" I said, I also felt like puking, something really weird was going on.
"I don't know... It hurts, like, everything" she said regaining balance.
I look at our surroundings everything was dark but there was a white glow that seemed to come out of Grace and me, it got even weirder by the time we got out. Sam and Tucker were both looking at us with wide eyes. Grace and I ignored them as we seat with our backs to the wall.
"What?!" I said annoyed by the stares Sam and Tucker were giving us.
"Haven't you seen yourselves?" said Tucker concern clear in his voice.
"Uh," said Grace, we both turn to face each other
"What the heck is wrong with your " I yelp 
"Oh God your face" She yelp. we both rushed forward to a mirror. We both scream at our sights.
"My hair and what freak happens to my eyes!" Grace yell.

Grace's POV(beware description time)
My blue eyes were now a bright neon green, my black long raven hair, was now white almost silver, my skin was a bit paler than usual, my clothes...well my blue jeans turn black, my black high tops turn silver ,and my short hoodie was half white half black and for some reason I have one black glove in the white part of the short hoodie and in the black part a white glove. Danny's change was the same as mine eyes color hair and the colors in his special suit (that I still didn't understand why he was wearing it since it was clear that it didn't help at all ) get inverted being black with silver boots and gloves, and we both had a kind of aura like we were glowing it was really weird.

Danny's POV
"Okay, guys how are you feeling?" Sam ask I knew she was scared out of her mind.
"...weird" Grace and I say in sync.
"Weird how?" Tucker asks. 

"I Dunno," Grace said her back pressed to the wall while she was hugging her knees burying her face in them, I turn towards her.

"You feel it two don't you?" I ask trying to understand what was happening.
"Yeah" she said slowly. "The dead?... coldness?" She said though it sounds more like a question.
"Yes, So I'm not crazy," I said triumphantly
"Well, maybe we are," said Sam. "Do you think you guys can go back to normal?"
"Don't know..." I said, At that moment Grace stood up and close her eyes in concentration.
"What ya doing?" I asked
"Well as Albert Einstein once said 'Imagination is more important than knowledge' so... if that's true I will imagine..." she was cut off by two blue rings that separate around her waist one going up the other down. She was back to normal.
"How do you do that!" I said amazed
"I dunno just think of turning back and... that's it" she said rubbing the back of her neck.
"Okay..."I concentrate and the same rings appeared around my waist and I grinned. "So... What are we going to do?"
"Can you guys turn back in your 'ghost form'?" Tucker said
"Ghost form..." Grace seems to be in deep thought. "Fuck, mom and dad!" She said worriedly, my grin melted as fear and realization cross my face.
"Oh, uh if we are 'half ghost' we don't know what our parents might do, we are Freaks they would hunt us down" I said scared out of my mind. "Just my luck we're a half ghost and our parents are ghost hunters. We can't tell even Jazz!" 
"You're right... you know what we will talk about this on Monday in school for now let's rest" grace said Sam, Tucker, and I nodded.
