Disclaimer: Harry Potter is not mine. Damn.

A/N: Wow, I finally finished the first chapter for this! It's taken a really long time. Readers of another story of mine may have noticed that I like the name Adrian. Anyway, this story is a bit of a departure from others I've written, but I really like it. It's AU, obviously, and reviews are very appreciated.

Lost Prophecy- Ch. 1 - Flesh and Blood

Harry Potter was not a happy boy.

Everyone else in #12, Grimmauld Place were slumbering peacefully, but he was lying awake, mentally berading himself. On top of all the usual problems he had todeal with, such as worries about school and friends, he had to deal with much more. The Dark Lord was still at large, and it was up to The Boy Who Lived to stop the great evil of the century. On top of that, there was a much more immediate, a much more destructive problem at hand. A problem that the raven haired boy would only acknowledge in the dead of night, when he was certain he was completly alone.

He was in love. This might not seem out of the ordinary, especially for someone of his age. But the girl who had his affections was not, under any circumstances,an appropriate consort. It was his sister. He was in love with his own sister.

Harry let out a frustrated sigh and beat his pillow with a clenched fist. It was too hot, everything was too damn hot. He was covered in a thin sheen of sweat that clung to his pale skin uncomfortably. He often lay like this, night after night, trying to convince himself that his feelings of lust for his own flesh and blood was just him trying to make up for the twelve years that he had lived without her. That was all...he was just trying unconsiously compensate for lost time.

'Twelve years,' mused Harry to himself in the darkness of his bedroom. How had he survived that long without her? When Dumbledore had first sat him down in his office and informed the boy that he had a living relative, a younger, secret sister, Harry's feelings had initially been somewhat mixed. Sure, having a surviving family member was wonderful, but would he be able to connect with her? To a twelve year old, the age difference of two years may as well have been two decades. But he needn't have worried. The moment he had laid eyes on her, he knew he loved her. There was an immediate connection between them, a connection that would only strenghthen with time.

Flashback

"I really don't want to do this," Harry said nervously to himself. He picked agitatedly at a loose thread on the hem of his shirt as he stood on the front lawn of a house that his Headmaster had just entered. In just a few moments he would meet her for the first time. It was strange just thinking about it.

"Why are you telling me now?" he had asked. Dumbledore had smiled patiently as he answered.

"Harry, your parents knew that they were in danger, though they did not know why. To better protect you, they placed your sister in my care, and made arrangments to give you to me when they were sure it was safe. Before they could do that, Voldemort murdered them and tried to murder you, and I decided the safest course of action was to place you in your relative's care."

Harry's lips parted to interupt. Dumbledore raised his hand to silence him.

" I know what you are going to ask, Mr. Potter. Why didn't I give them your sister, as well? It was beyond my ability at the time to place a magical protection on both of you, and since you were the one in the most jeopardy, I decided you were the priority. So I placed her with a lovely Muggle family and waited for the day she would come of the age to attend Hogwarts. And that day," finished the Headmaster with a serene smile, " is today. Any questions?"

Questions? Of course Harry had questions! Even to his twelve year old mind, that story had gaping holes in it. But he was overwhelmed with the new information, and he could barely form a coherent question before it flitted away in a confused haze. Later, Harry realized the old man must have Confunded him. Before he could inquire the Headmaster's motives further, the man looked up with a satisfied look.

"Ah, here she is. Be nice, Mr. Potter."

Before them was a young man who couldn't have been more than twenty five, leading a little girl by the hand gently towards them. She looked almost exactly like Harry did- jet black hair she kept long and unstyled, pale skin and startling green eyes. The only differences between them were her eyes: intead of emerald green, hers were the color of seafoam, a light blue-green. The Boy Who Lived swallowed as nervous beads of sweat began to form on his body.

The pair drew closer and Dumbledore rose his hand in greeting. Harry wiped his hands nervously on his jeans. He wasn't ready for this. Not at all.

"Ah, Roger. And Adriana! How are you today?"

"Fine, thank you, Albus. Adriana, aren't you going to be polite and answer him?"

The girl said nothing and stared at Harry curiously.

It was then that he knew.

Beyond a shadow of a doubt, he knew.

Dumbledore nudged him and he stumbled forward awkwardly.

"H-hi," he stammered shyly. "I'm, uh, Harry. Harry Potter."

His sister smiled a smile that lit up her entire face. "Hi," she whispered. "I'm Adriana. It's nice to meet you."

End Flashback

Harry smiled to himself in the darkness of his room. They had both been so nervous, but they needn't have been. Before the day was over, Roger and Dumbledore had noted amusedly that the pair were inseperable.

"Harry?"

The Boy Who Lived sat up in his bed and looked at his door.

"Adriana? What's wrong?" His door opened slowly and his sister entered. Harry swallowed as every drop of moisture left his mouth, and wished he was wearing something besides his pajama bottoms. She had been in his room for perhaps a second and he already could not keep his eyes off of her. She had changed a lot during the five years since they met. Gone was the androgynous little girl figure- she was really developing into a woman. A woman with long legs, perfect breasts...

'Stop it,' thought Harry angrily. 'What is wrong with you?'

"Did I wake you?" she asked quietly, interupting his lewd thoughts.

Harry shook his head. "No, not at all. What's wrong, Adriana? Did you...have another dream?"

Her eyes filled with tears as she threw herself onto his bed, into his arms. Harry sighed as he held her, and wondered why he felt so dirty.

"It's alright," he whispered soothingly, kissing her tenderly on the forehead. "Tell me all about it."

End Chapter 1.
