Cherry Green is haunted by what appears to be delusions that are turning her life upside down. She cannot come to terms with the fact that they could be more than just her mind playing tricks on her.
Events in her personal life force her to go back to Swallow Town. She is forced to break bread with an overbearing mother who she loathes or be evicted from her home. Moving into her late sister's old home seemed to be a good idea for Cherry, until the entity stalking her starts to manifest itself even more forcefully.
She does not know the entity's presence is tied to an old relic in her possession. It is the reposition of curses. it is the Judas coin.
