Bad people come out at night. And those bad people had better pray that they don’t run into Freya Flynn, because Freya is on a mission to punish the wicked…. Freya’s past is about to catch up with her, in the form of a threatening letter from persons unknown. This person knows all about her past and what she does on her night walks. This person is also making sick and twisted demands of her, and if she doesn’t complete the disturbing tasks that they have set, then someone close to her will die. Who is the mysterious letter-writer, and how far will Freya go to protect the people she has come to care about? This is extreme horror, please proceed with caution.
