Exile

Brief Synopsis: During the 17th Century, a "comfort woman" named Beatrice exiles to a small shack in the woods with her two young children after being accused as a witch. Over the course of their stay they encounter several demonic figures in the form of different animals such as a snake and an eagle. Because of this Beatrice increasingly starts to become paranoid, believing that her two children are "demonic".

Ending: Beatrice is burned inside the shack by the townspeople who had recently discovered her whereabouts.

*I'd think this would be a short novel consisting of less than 200 pages.
