Sisters of Magic

I ran harder through an alley, the cops were on my tail because I blew up an apartment...again.
With my I'll probably end up in jail, but they'd have to catch me first. I ran harder, and faster, until I ran right into something a lot worse than the cops. Dog, big dog.
"Hellhound!" I screamed. I ran even harder now, left, right, no left!
I ran into a dead end.
I was trapped.
I didn't have anything to protect myself with but...no never again.
I'd rather die then do that again.
The monster advanced, and right when it was about to attack it froze and exploded into yellow dust.
A young girl maybe 13 or 14 was holding a long sword.
I definitely liked this girl.
"Are you all right?" The girl said in a old accent, roman I think.
"Yeah, I'm fine." I said.
"Good, I'm Tara." She told me. "We have to get you to camp."
" I'm Aura, and do you mean Camp Half-Blood?" I asked.
"You've heard of it?" Tara asked me.
"Yeah, I send young Demigods over the border all the time." I told Tara. "I am a child of Hecate, Goddess of Witchcraft and Magic."
