The Demigod Tales part 1: I create a purple wall

If you’re like me, stop reading immediately and come. Don’t start reading this, because it’ll just slow you down. Just drop the book, grab the most important stuff and come to us. You know, what I mean.
If you’re just an ordinary mortal person, then just keep reading. You might think it sounds exciting, but believe me: You don’t want to stand in front of these creatures for real. Now you know. So: Let me introduce myself:

My name’s Zia. I’m 15 years old, and what the society would call a ‘troubled kid’. Why? I’m dyslexic, I’ve got ADHD and I’ve been thrown out of every single school, I’ve ever been in after one year. But it wasn’t before 9th grade, everything really started to go wrong. And it started like this:

A few months ago, my class was going on a trip.  It was me, my classmates and the two teachers in school I hated most; all of us on a trip to ‘Ye Old Museum for Boring Stuff’ - apparently. It was a killer! And of course did all the popular kids immediate get their best friends as partners, so I ended up being with Tyler Beckfield, a big, strong boy with black, spiky hair, gangster-clothes and dark eyes, who thought it made him cool to flirt with every single girl in school and at the same time be the biggest idiot in the whole entire history of idiots.
I was no exception.

At the whole entire trip, he was trying to take my hand, put his hand on my shoulder and give me compliments, but I knew, it was just to be cool.
When we came to the part of the museum with clothes, it really started to be gross. Tyler put his arm around my shoulder and half said half whispered: “Why do we waste our time here. Let’s just leave, shall we?” And then he tried to kiss me!
“Back of you creep!” I yelled and ripped his arm off my shoulder. But either I was stronger that I toughed, or he was just being overdramatic, because he took to his arm and screamed in pain.
“I was just asking her something about the exhibition.” he said with shaking voice. The other student started to back away, but my science teacher, Mr. Wright - a huge, strong, and buzzed man in about 45 years started to go closer.
“Zia.” he said with his most ‘Relax, you will get your medicine in a minute’-ish voice. “You obviously forgot to take your ADHD-medicine earlier. Come with me, and you can get it.” He started to move towards me, but I started stepping away from him at the same time.
“No!” I said. “I did remember! Go away from me!” But he just kept moving towards me and raised his hand - which was about the size of a shovel - like he wanted to grab me.
I stopped. “I said,” I yelled. “BACK OFF!” When I spoke the last words, I raised my hands, and something really strange and directly scary happened: A stream of purple energy flowed out of my hands and created a wall between me and my teacher.
The other kids screamed; even Tyler stopped feeling sorry for himself and starred at me with a mix of excitement, fear and disbelief in his face.
The other teacher, Miss Tommilton started moving towards me slowly, but another person was faster; a girl came running out of the group of my stunned classmates and towards me. I didn’t know her so well, but I knew that her name was Kyla, and used crutches, because she was lame from the waist and down. But now, she ran faster that I’ve ever seen anyone in our class run ever before. I got so surprised, that the wall disappeared and the teachers could move towards me again.
They didn’t even get the chance.
Kyla sprinted past both of them, grabbed my wrist and pulled me out of the museum. Behind us, I could hear Mr. Wright yell my and Kyla’s names, but Kyla had already flagged down a taxi and pulled me into the back seat. The strange was that Mr. Wright’s voice had changed. The yell sounded more like… A growl. Kyla gave the driver a stack of dollars and told him to press the throttle, and then we raced away from the museum with 75 km /h. I didn’t know at that time, but that was the last time, I would ever see my classmates.
