Mistakes and Promises takes place in 1996 up to early 1997, during Harry's sixth year of Hogwarts. It focuses on a middle aged witch named Skyla Lamar who is a Death Eater and double agent. She didn't always want to be a Death Eater, however. Unlike many of her fellow Slytherins, Skyla wanted to become an Auror and be responsible for putting Death Eaters in Azkaban, not the other way around. Throughout the story, Skyla is constantly reminded of her past mistakes as she attempts to "fix" them in whatever way she can. However, her biggest mistake is something that can never be fixed.
