A/N: Hi guys! So this is my first fan fiction in English, so I'm sorry if I make mistakes. I'm not a genius...

Back to the story, so like I said it, English is not my first language, so be indulgent please. Don't hesitate to PM me if you have suggestions about the story.

First, Harry is in his seventh year, and as you must know, it's placed after the second Giant War and what else? ANDROMEDA! I totally forgot about her! OMGS! Anyways, Andromeda Dawn is... special. She's sixteen, like Nico, and she's at Camp Half Blood since 5. She had long dark brown hair and brown eyes.

This is a little text about Andromeda. Hope you like it :)

Disclaimer : I don't own any of this.

Andromeda's story:

She was living with her mother Diana Dawn. Her mom always cares about her daughter like her own life, and Diana wasn't a mortal, in fact, she was a demigod, a daughter of Bellona, the roman goddess of war. One day, her mum decides that Andromeda and her must go to Long Island, to take a break, because Diana and Andromeda Dawn where living in San Francisco. When they went to the hotel, an empousai attacked her and her mother, at first, Diana thought it'll be easy, but, in the end, little Andromeda saw her mom dying in front of her eyes.

With revenge in her mind, she took her mother's sword and killed the empousai. In the moment, at the same hotel, a satyr, Mitchell, saw Andromeda's mom died and her, killing the empousai. He was surprised, how could a little girl, who had never seen a sword or a weapon before, killed an empousai in about 30 seconds? He brings her at camp, and, at her surprise, Chiron knew her mother, and tells her that she's a Greek demigod, and also tells her that her mother was a Roman demigod, daughter of Bellona. The same night, she was claimed by Ares. And also the same night, her father appeared in front of her and gives her a ring, a magical one; he said that he created it with the help of Hephaestus for her. That ring can change form of any weapons in the world, and if she lost it, it always reappeared in one of her fingers. (A/N: Like Riptide :)) Though the years, she became the most powerful Ares Kid, and maybe the most powerful demigod in the camp. When Clarisse came, the two girls immediately became bffs.

At the Titan War, she lost many friends, that she'd think that it was just a nightmare.

After, she began to fall in love with Bryan McNight, a son of Demeter. At first, her brothers and sisters laugh at her and her "love" but they soon realized that they were truly in love. She was happy. But ... In the Giant War, she lost him. He died. Like a hero, to protect her. He died when she was about de die, he took her place. And after that, Andromeda wasn't the same. The whole camp tried to comfort her, in vain. Annabeth tried, Piper and all the experts of love, tried, but still nothing. She became to act like Nico Di Angelo. She was being little rude sometimes, she was cold with anyone who doesn't know her like she know herself. All the people in the camp will always remember the Andromeda before the 'incident', always smiling, always happy. For an Ares Kid, she was nice. Actually very nice with everyone, her fatal flow? Generosity, or was. Now, her fatal flaw is revenge, because she'd never admit it, but she still wants more. She wants more revenge. If she had the occasion to revenge on anything in the world, an excuse to revenge on something or someone, she'll do it with no regrets.

Actually, she never met Nico Di Angelo. Before being the 'new' Andromeda, she always wanted to meet him, for her he sounds so mysterious, creepy and scary, but she wasn't like the other, she wasn't scared, she just wanted to know him, not the son of Hades or the Ghost King who scared everyone because of your father. And even after the 'incident', she always wanted to know him.

And then, Chiron calls her to the Big House.

So? Did you like it? I know, it's a little text but hey! I didn't finish yet.

Here the prologue:

Prologue

'Andromeda!'

I turned to see who it was.

'Hi Annabeth'

Annabeth is older than me; she's like my old sister. She's one of the people in my life who know me. Who know me like myself? Yes.

'Chiron wants you in the Big House, now!'

I ran to the Big House. If Annabeth said that Chiron wants me, so it's important.

I knocked at the door and Chiron opened it.

'Good morning Andromeda, come in'

I came inside the house and sat at the Ping pong table. I was shocked, because in front of me was Nico, Nico Di Angelo, with his dark brown hair, like mine his dark eyes full of darkness and his pale skin. He had the same ring at his finger, the black one with the skull on it; he had the same clothes like every day: Black shirt with black pants and his aviator jacket.

He looked at me like he was going to eat me, he thought that I was scared of him, but I wasn't. And for show him that I'm not scared, I looked him in the eye. He was surprised.

'So, do you know why I bring you here, demigods?'

"No" I said,

'What do you know about wizards?'

A/N: Mouahahahaha * smile mischievous *.

I'm in love with my own story!

So this is a little chapter, in fact, it's just a prologue + Andromeda's story.
