My title says what I am looking for honestly, but I will go into some detail. The story I am writing is a supernatural existence overplayed on reality story. Good examples of this are common enough, Percy Jackson and the half blood camp existing in a world that is still our own however is more than our own. Hogwarts existing in a homely little English countryside even though humans know nothing of magic and don't notice it. My story is more so about paranormal forces, specters, demons, and most importantly, ghosts and mediums. The key aspect of my story though is the Main Character and her journey for vengeance. She is new to the paranormal world that lays over top the normal, and soon after her delving into this foreign land which exists within her own, her sister, who has been in the paranormal aspect for some time, is murdered. In a quest for power, the villain slays the sister in search for his own personal and selfish goals. This causes a quest for vengeance in my Main character, against the antagonist. However, I am not sure what to include in this story. What is a good Revenge story not complete without, or what is so common in a revenge story I should forgo it and try for something new?
