A/N: This is my first fanfiction, so please R&R. Other than that, grab your popcorn, kick back and enjoy the show.

Not many people knew that the famous Auror James Potter had a twin sister- also an Auror, just not as well known. Fewer still that she had a two-year-old son, or that two days ago she gave birth to another son, Harry Potter.

James Potter's POV – 15 years ago

James heard a knock on his front door, and went to open it. And his jaw hit the floor. His new born nephew was on his front porch. What in Merlin's name was he doing there? And where was Felicia? Still surprised, he picked him up and carried him into the sitting room where Lily was.

"Is that…?" his red haired wife asked.

"Harry. He was just lying there, on the porch, with Felicia nowhere in sight. I'm worried- it's not like her for her to just leave her son." He replied, worry etched on his face.

Their questions were answered by the morning newspaper in the most tragic way.

The house of Felicia Potter had a Dark Mark hovering over it. But her eldest son was nowhere to be found.

Poseidon's POV – 15 years ago (same night)

There was a crash as the front door was kicked in. He and Felicia were in the nursery, about to put their newest son to sleep.

"Death Eaters! Grab Percy and go! Go!" the mother cried, pulling out her wand.

Poseidon shifted Harry into one arm, and picked up Percy. "But what about you?" he asked, worry for her creeping into his voice.

"This is what I do best, Poseidon. Now GO!" she replied as the Death Eaters thundered up the stairs.

That was the last time Poseidon ever saw Felicia Potter alive.

He reappeared on James Potter's doorstep. He set Harry down- James was his godfather. He would have set Percy down too, but it would be safer if they were apart. That way, Death Eaters wouldn't get them both at once. He knocked and reappeared outside a New York City apartment door.

Sally Jackson was a good friend of his. Poseidon left Percy with her. He would have raised the boys himself, but the ancient laws forbid that.

He returned to Olympus, wrote a letter to Albus Dumbledore, leader of the Order of the Phoenix, and Severus Snape, Percy's godfather. (He didn't leave Percy with Severus because it was too dangerous, him being a spy within Voldemort's ranks) Putting the letters in an envelope addressed to Albus, he hid it in Felicia's journal.

Albus Dumbledore's POV – Present Day, anniversary of Felicia Potter's death

Albus sighed. 15 years ago, on this very day, Felicia Potter had died. She had been one of his favourite students. Opening his desk drawer, he pulled out a journal that had belonged to Felicia. Only recently had it fallen into his care, as one of her friends had possessed it until she had passed on just last week. (The friend in question had gotten all of Felicia's stuff) Albus opened it to the first page. To his surprise, there was an envelope addressed to him-and it wasn't in Felicia's handwriting. Opening it, he found another letter addressed to Severus Snape- he and Felicia had become good friends while in the Order (Much to her brother's irritation.). Puzzled, he summoned the Potions teacher to his office.

"Severus, somebody has left us letters, and left them in Felicia's journal." Albus told him upon his arrival.

August 2, 1999

Professor Dumbledore-

As you know, Felicia had two sons: Harry and Percy Potter. I am their father. I was with Felicia today, when the Death Eaters came calling. She told me to take our sons and go. And I did, and I regret leaving her to face the Death Eaters, but she told me "This is what I do best." I left Harry on his Uncle James' doorstep, and took Percy to a good friend of mine in New York City, Sally Jackson. I split the children up, so that if Death Eater's came for them, they would not get them both. I would have raised them myself, but the ancient laws forbid doing that.

P.

Severus had received a similar letter, but it explained why the father had not left Percy with his godfather as well.

Severus looked up from his own letter. "Do you believe it?"

Albus smiled. "It certainly does explain a few things. Such as, how did Harry end up on James' doorstep, or why Percy's body was never found. I think we should pay this Sally Jackson a visit."

"All this time….I thought my godson was dead. Does he even know he's a wizard? Or that he has brother?"

"I do not know. What I do know is that you should be the one to find him. He'll be seventeen now."

A/N: Please R&R! I will take any questions about myself and post the answers in A/N's and on my profile page. I am also in need of a beta, so I will be taking volunteers for that position as well.
