My Mysterious Life; Book 1

Help me...

Sylvia ran home after what had happened which means I had some time to explore the rest of this island before it got dark by myself. Suddenly, I saw a boat... it was coming toward this island!! Oh god. I gripped tightly onto a branch above me and swung up.
The boat approached... it anchored a few feet away from the island. I saw a man that looked like he had a tuxedo on get off the boat. A girl hopped out behind him, she had a baby blue crop and high-waisted shorts on. She had beautiful,wavy, pale pink, hair that extended to her shoulders. The man had slick-back , shiny, brown hair that was short (of course).
"Shawny, did u have to wear the tux? Like, we're on a fucking island!" The girl said. "Of course, Lily! I must not dress ragged anytime!" He replied.
I know that name, I just can't put my finger on where I know it from...She rolled her eyes. "You never know how to have fun." She mumbled.
I started leaning towards the ground to see 'Lily' and her face. I slipped a little and the branch shakes. It wasn't stable enough to hold me for much longer. "What was that?" Lily seemed panicking. I stood up on the branch and jumped down, tackling 'shawny'. He spun around. I gripped his shoulders, he tried to throw me off so I reached for his pressure point. "Riley?!? Is that you?!?!" I heard her scream. Before I reached his pressure point, he slapped my cheek. He ripped me off his back and cradled me in his arms. I frantically tried to get out of his arms, he had a strong grip. "You know this rude as fuck little brat?" He said. I glared at him. "I'm... I don't know... maybe..." she said hesitantly. He threw me up against the wall. "Ouch man, why you gotta be such a douche?" "Excuse me?" He yelled. He forced me up by my hair. "Why are you being a BITCH?" He shoved me up against the wall and started strangling me. As I struggled for air, I used a technique I learned in "Arts of Defense". I grabbed his hand and weakly, I put as much pressure as possible on the part of his hand about 1 inch below his thumb. He stopped. I fell to the ground, air forcing its way into my lungs. I rubbed my neck. "Riley!" Lily yelled. She punched Shawny in the arm and ran over to me. "Oh god! Her neck is all red!!" She shrieked. I coughed. It hurt to cough. Something dripped down my chin. "Oh god! She's coughing blood! Someone help!" And with that, she vanished and I was swept away by the darkness.
