Ghost In My Bedroom (Muke Fic)

I made a brand of my own poison that I gave to you
It was the first of my experiments I’m going to put you through
Now it’ll only make you dizzy, sick, and paralyzed
I think you’ll live without the antidote, the ending’s a surprise
-OR-
Luke and his parents have just moved house, and lucky Luke, there’s a surprise living in his bedroom.
