Because It Is My Blood

A life-sucking knife in the hands of one girl. A hidden society full of mystery. A super undescriptive description.

Zafira, born with schizophrenia, has a ghost twin brother.
Ella, adopted and deprived since birth, has a pain in the neck.
Jamie, the said pain in the neck, coupled with Sydney, another pain in the neck, must save Zafira and the knife, but since they're (obviously) idiotic, they drag Ella into the previously mentioned society.

How complicated can a simple problem become?
Answer: Very, very complicated.
