I hit my fingers against the desk as I tried to manage through my algebra class. I sighed and looked up at the ceiling. How did my brother even get me to agree to take this class. I wasn't as smart as him. Yes my brother is the rich, famous Tony Stark. Not many people knew that he had sisters, but our dad thought it was best to keep us away from the press.

"Miss. Stark. Miss Stark!" my teacher yelled. I snapped out of my trance. "X = 53!" I blurted out as I sat up straight. The entire class giggled, my teacher looked suspicious. "Glad to see you're paying attention Miss Stark. Now as I was saying the y-axis is the~ BRING!" The bell went off signifying the end of the day.

I dashed out of the class room, sprinted down the hall, then skidded to a stop at my locker where I whipped in the combination and grabbed my backpack. I walked to the back doors where I waited for my sisters. We attended Goldman's middle school in Indiana, I was in 7th grade along with my two triplet sisters, Ella and Taylor. I saw Ella's familiar dark brown curls.

"Hey, Katelyn." she said in her usual quiet meek voice "How was algebra?"

I hit my head against the wall "Stupid." I mumbled.

"Have you seen Taylor anywhere?" I asked. Ella shook her head "She should be coming from gym class, so she's either coming out or in the principles office for inappropriately throwing a dodge ball."

I smirked and relaxed, leaning back against the wall. Right when I was relaxed, out of no where "Boo!" a voice yelled behind me. I jumped I turned around to see Taylor with a smirk on her face. My eyes were wide and I felt something bubble inside of me. 'No' I told myself 'Not now, not here, not ever again'

"Taylor don't do that!" Ella yelled at her. "You know what happens when Kate...you know." Taylor's brown blonde highlighted hair was mangled around her head. I glared at her, "Let's just go." I said.

Ella and Taylor cast worried looks at me as we started walking toward our house, where our nanny was waiting. We walked a good distance when a black van, with a red horse with the word FITE on it, pulled up beside us. In a split second a man came out of a van and grabbed us.

We were thrown into the back of the vehicle, gagged, and bound. "These girls will make excellent lab rats for the Dr." said one man with a thick foreign accent. Panic quickly rose to my chest , I left my phone in my backpack which was back at the curb.

I looked to my sisters who were in no better condition than I, both wide-eyed and frantic. I looked to around the trunk, there were no windows, no light, no...anything. I drawled a breath through the dirty rag that covered my mouth, the air was stuffy but we were, able to breath.

I sank down and slowly fell into a light slumber

I awoke to a loud bang. My head hit against the metal wall, I was pretty sure that I got a good size bump.

I groggy sat up, I was in a car a moving one. I panicked until the memories from earlier today slowly entered my head. I groaned by it was muffled by the cloth over my mouth.

The car halted to a stop, I was thrown forward I rammed into Ella, then Taylor was thrown on top of us. The back door was opened and two men came into view. The men were unkempt, raggy, and smelly.

They threw us over their shoulders and brought us to a strange lab. The lap was high tech. but at the same time...not. We were thrown onto a single tables and strapped down.

One of the men came up to me with a syringe in his hand. He gave he a cruel smile, his shackling bright blue eyes had evil written over them, and stuck it into my collarbone. It felt like a thousand hot knifes pierced my skin, pain course through my entire body. I let out a scream only to be be muffled by the gag. Even once he removed the syringe.

God it hurt to move, I mustered up enough courage to turn my head over. I felt anger and something strange bubble inside. Ella's once blue eyes were now silver and wide with terror. Taylor and a red mark on her cheek in the shape of a hand and tears threatening to pour down her face.

I glared at the men with my new-found courage, 'They messed with the wrong family!' I thought before another sensation reached my skin. It was almost like my skin was on fire, I gripped my eyes shut knowing what was coming next.

What happened next was almost to fast to remember, in my place now was a creäture. A cat as tall as a human standing on her hind legs, dark black brown tabby fur slightly ruffled and sickly yellow eyes scanning the room.

One man yelled something in a foreign language charging at the Cat. That's what I call the beast. But she swiped her hand and the man fell to the ground bleeding from the deathly wound on his neck.

More men charged at her yet she took them out as if they were fly's, killing left and right. 'Stop it!' I yelled 'That's enough! You don't need to kill them!' 'Oh, but I do. You may not know it now Katelyn Stark but if you do not dispose of your enemy's they will only get stronger.'

'Let. Me. Out!' I yelled, pushing out of the dark trap. I found my self on the floor, I looked around. It was the lap, the men were all on the floor dead. Ella and Taylor were~ Oh my god! Ella and Taylor!

I stood up fast, only to become light-headed and fall back to my knees. I gripped the table for balance as I slowly stood up. "Ella! Taylor!" I yelled, even though it burned my through. They were looking at me with wide eyes, fear written on their face.

I quickly undid their bonds, I looked down at the floor. "I am so so sorry." I said in a hoarse voice "I should never have lost control like that." I felt tears streaming down my face as a hand touched my shoulder.

"It wasn't your fault Kate," Taylor said "Plus you beat their ass." Ella gasped "Taylor! Language!"

I cracked a smile, but it didn't reach my eyes. With out warning men in combat suits barged into the room, they looked around spotting us. "We found them." he shouted into a walkie-talkie

I sat in one of the chairs at the local police station, the men had questioned us about what we saw. Ella had a blank expression on her face as she sat down next to me and Taylor.

All of us jumped when we heard shouting down the hall. "Look buddy, I don't care if it's visiting hours or not. I flew all the way from NYC to come here, because some psychopath company kidnapped and experimented on my baby sisters. I haven't had a cheeseburger in ages so I really don't want to hear a god damn this except 'Tony Stark your sisters are okay and here's your cheese burger and side of fries with a large coke'! Kay?"

Tony then stormed into the room, eyes immediately landing on us. He let out a sigh of relief "Thank god you three are alright." he said pulling us into a giant hug. "Don't ever do that again. Do you understand? The next time you see a suspicious looking black van I want you to blow it up."

I didn't say anything just buried my head into Tony's chest, "Pepper's got the limo out side waiting for us and cheeseburgers." he said after a while.

"Do they have bacon?" Taylor asked, Tony smiled "Well they did." I sighed again the days events flashing in my mind, I made myself a promise that day. That I would do anything for my family to keep them safe.
