When the Sky is Black (A Sad Story)

Who would've known this would happen?
April clung her little arms around my waist, sobbing with me under the heavy concrete overpass, and the 50 mph will blew us against the wall. The sky was the darkest black; even at two p.m.
"Hang in there, April! Please!" I screamed, half to April and half to the sky. The huge, flying gray machines swooped down to the highway, and April screamed.
I heard a beep gradually becoming louder, faster, louder, faster. It came from the flying machines.
"Make it stop, Paige! Make it stop!" April cried, her sobs piercing into my brain. Hearing that was more painful than the beeping of the machines.
The other people under the overpass screamed. The wind blew up almost at 80 mph, and I could feel myself flattening and cracking my ribs during the process.
The machines flew under the overpass. A few of them sucked up the other people in a green light in the bottom. April shook so much that I could feel it above the wind.
No more mother. She died right after giving birth to my nine year old sister, a long, painful death of blood.
No more father. A few days after my mother passed away, he left April and I; So, even though I'm only fifteen, I am raising my sister.
I felt a cold tear roll down my face, but it flew away with the wind. One of the machines flew right above us. It's green light opened right in front of us.
I screamed. I felt April's grip losen, and her feet left the ground. I held on with all my might.
"Paige!" She yelled. "Let me go! Save yourself!"
I sobbed, my chest heaving as a car blew past us. "No! Never! I... I can't!"
"I love you." She mouthed. Both of her little hands left my wrists.
She flew upside down into the green light. It closed, and zoomed up into the sky.
"April!" I screamed. Three times. Ten times. One hundred times.
I saw a hole in the cement wall, and I climbed in. It went back a few feet, so the wind didn't blow right in my face.
I sobbed at the top of my lungs, because, while people were being dragged to a parallel universe of some sort out there, I was alone.
