Lucy's Eyes

Lucy is an average, insane girl who has lived in an asylum with her supposed invisible sister, Liz or Lizzy, for about 7 years because of her diagnosis of having an inherited schizophrenia from her dad. She tried to kill her grandmother by stabbing her with a butter knife at the age of 4. She is now 13. She and Libby want to escape and they have a chance when the dark monster they drew together starts killing all the nurses and doctors or anything that moves, then ripping their eyeballs out. Lucy is afraid but Lizzy is enthusiastic. They run but they are on the 50th floor since they were to be there for the rest of their lives, but that's gonna change. Or is it gonna be the same nightmare they'd been facing on the inside of captivity. Will anything be different?
