Melissa Waters is a mermaid who has seen so much. She has seen the Earth change through many years, but has never been involved in it. She has kept to herself all of her life and no one knows about the 19 year old girl living on an island that is right under their noses. Well...I wouldn't say she's 19, but I'm getting ahead of myself. So what will happen when a certain TARDIS stumbles upon this island. Will Melissa let her walls down enough to welcome the doctor enough to tell him who and what she really is? What will happen when the Doctor "accidentally" takes her away on the adventure of her life? Will he find the cure to her loneliness? After all, she does need a doctor... (This is the rewritten and improved version of my previous "A Tail and A TARDIS". I don't own anything, I just own the plot of the story and my OC. I don't own the Doctor, the TARDIS, or any of the other characters of Doctor Who. Although I wish I did...)
