Shadow people

Disregarded, and forgotten, Loki and Alexandra had that in common. They were both born and raised in shadows.
She had been having a normal life, but all of that changes when she awakens in a nordic afterlife, in this place called Valhalla. She is then offered a position in Asgard, serving Odin and his family. Now you would think it couldn't get any weirder, but it does. She has befriended Thor and Loki, children of Odin. Well, Loki is a bit of a different situation. Perhaps a bit more... friendly.
PREVIEW:
A high-pitch scream rang through the once silent, peaceful campus, a gunshot and a quiet thump. My heart leapt into my throat, I bolted out of the building. The world had turned to chaos, more gunshots, more screaming. My fellow classmates fell dead in front of me, as I searched for the source of the shots. She held a small silver and black handgun and had a crazed look in her eyes. As if of its own accord my hand reached into a pocket of my jacket and pulled from its folds my dad's small hunting knife. "Hey, I just want to talk, okay?" I said faking a confidence I did not possess. She mumbled something to herself, I couldn't hear what. A fiery heat shot up my leg. I fell to my knees, gasping for breath, somehow I held myself alright. Ignoring the flaming protesting from my leg. In one swift movement my knife slammed (flat blade side) onto her armed hand. She dropped the gun. "Please, I don't want to hurt you, but I also cannot let you hurt anyone else." She lunged, her clammy hands clenched around my throat until there was no more breath. She finally released her grasp and I limply fell to the concrete. She held the gun again, and a shot cracked the sky. A bullet imbedded itself in my collarbone. Tears streamed down my cheeks, "I am so, so sorry." With all of my remaining strength, I shoved my blade into her abdomen. A wretched scream rocked the sky. I fell, back onto the cold, hard stone.
