What if Mal had a little sister that she left on the Isle of the Lost? A little sister that no one off the island knew existed. One that can slip between the cracks unnoticed. One that was cunning and full of tricks. One that could never seem to keep her temper in check and was always causing trouble for everybody. Mel always adored her sister, but didn't want to be in her shadow. She was every bit as strong and evil as Mal was, but no one ever payed her a bit of attention except for her sister, Jay, Carlos, Evie...and their dad. Their mom acted as if she didn't exist at all. She tried to get her attention by causing as much trouble as she could around the island, but it was never enough. Maleficent was always working on making Mal better. Now Mal's gone and all of the attention is still on her and the people she considered family were gone. How will Mel handle this next chapter in her life? And will she ever get her own happily ever after? ***This is my first fanfic, so please be patient with me. I just haven't been able to get the idea of her having a sister back at the isle out of my head. So, I'm going to give it a go and see what happens. Also know that I looked up Hades daughter and the first name to pop up was 'Melinoe' so I just shortened that to Mel. From what little I looked up she could only possibly be Hades daughter, but it her mean mean "The Black One" and she is said to give people nightmares. Please don't attack me. I'm usually good with original stories. I just don't know about fanfics. And I obviously don't own Descendants or the characters in any of the franchise and I am only saying that once.
