So my main character (Rayhne) has no memory of her childhood before she was 11. Right now I have the story starting off Chapter 1 with her using the full moon's powers to get some of her memory back. The readers know that she has gotten something but it is like a dream and fades really fast. So my question is: Should I do a prologue where I actually show what memory she pulled? It is the memory that started it all so it would be useful. However I do not wish to start the first chapter with it because it takes away from Rayhne's terror. So prologue or no?
