Chapter 1

"Do you really think this will work?" James asked his wife. Lily had her nose buried deep into a book and was jotting down notes on a piece of parchment.

"It's the only thing we haven't tried. All the book says that out of all of them, she is a protector of children. Despite being an eternal maiden she is the goddess of childbirth. She's the best hope we have," Lily explained closing the book and setting her quill aside with a sigh. James immediately pulled his wife into a hug.

"Then let's believe in her," James whispered and Lily nodded. Together they sat in front of the fire and bowed their heads.

"Lady Artemis. Goddess of the hunt, wild animals, wilderness, virginity, and childbirth please hear our prayers and accept our offerings," James and Lily spoke as one as they threw their various offerings into the fireplace. Neither knew what they should give to a goddess so they gave a variety of things. The first item was a basket of the best fruits and vegetables the couple had been growing. The second item was honeysuckle and a branch of a flowering almond plant. The third item was necklace, a simple moonstone charm on a black leather chord. The fourth item was divided into two parts. The first was a pair of goblin made silver daggers. The second was a goblin made silver bow and a quiver of silver arrows charmed to always return to the quiver.

"Lady Artemis," James took over the prayer, "we know you are the goddess of maidenhood, and that asking you to do this goes against that."

"But you are also the goddess of childbirth. My husband and I are unable to have a child of our own. We would give anything to have a child. Please Lady Artemis. Grant us a child of our own," Lily finished the prayer as a gust of wind swept through the room and extinguished the fire.

"I really hope that is a good sign," James said, pulling Lily close to him as they stared at the empty fireplace. Not even ash was left.

Sally Jackson was at the beach with her lover, Poseidon. The same beach they met at actually, Montauk. But even though she should be happy she wasn't. Poseidon had broached the subject of having a child and Sally had to explain that she was unlikely to ever conceive, let alone carry the baby to term.

"I was in a car accident when I was eighteen," Sally explained. "My uterus was cut by shrapnel and was damaged. The doctors sewed it but it's unlikely I could ever get pregnant. If I did, trying to have the baby would most likely result in a miscarriage," Sally couldn't look at Poseidon. She was afraid to see the look on his face, the disappointment that she couldn't give him a child.

"Hey now. Don't think like that," Poseidon told her, wiping away a tear that Sally didn't even notice she had shed. "If a child is what you want, I think I can help. The twins. They owe me a couple favors. I can talk to them and see what they can do. Apollo is the god of healing and Artemis is the goddess of childbirth. I'm sure between the three of us we can figure something out," Poseidon told her gently. Sally wiped her tears and turned so she was facing Poseidon fully.

"But won't you be breaking your oath? And what about your wife? Won't she be mad at you?" Sally asked concerned. Poseidon shook his head.

"Amphitrite already knows about you. She actually wants to meet you sometime. Says any mortal able to catch my attention must be amazing. And Zeus already broke his oath twice. If he tries anything then it will start a war," Poseidon explained. "I love you Sally. And if anyone deserves the happiness of a child, it's you." Sally didn't know what to say, so she simply said nothing and leaned forward into his arms.

"I would love for us to have a child," Sally whispered. Poseidon nodded with a smile.

"Then I think I should get busy," he told her while standing up. Sally knew this was her cue to close her eyes. Sure enough, when she opened them moments later, Poseidon was gone. Sally couldn't help herself. She prayed that Artemis and Apollo would be able to help them have a child.

Poseidon knew exactly where to find Apollo, so that's where he went first. The Sun god was driving the chariot over California when Poseidon appeared in the passenger seat. If asked, both would deny the squeal Apollo gave upon being joined by his uncle, and the sudden nosedive the chariot took before it was quickly righted again. Apollo denied it out of a sense of pride and Poseidon out of a sense of future blackmail.

Poseidon didn't waste any time, instead telling Apollo to take them to Artemis and he'd explain when they were alone. Something in his expression must have betrayed his anxiousness because Apollo didn't make any jokes.

"You want us to help that mortal have a child," Apollo guessed. At Poseidon's confusion he continued, "She just prayed to us. Come on, Arty is waiting."

Apollo then set the chariot to autopilot and flashed away with Poseidon. They appeared in a field, where Artemis was waiting for them. That wasn't so unusual. However, the expression on the goddess' face was. Artemis was sitting in the grass, several items scattered in front of her. A basket of fruits and vegetables, honeysuckle, a branch covered in flowers, a necklace, a bow with a quiver of arrows, and two daggers laid in the grass while Artemis looked at them with an unreadable expression.

"Three mortals prayed to me today. A couple from the magical side and your Sally Jackson," Artemis spoke up. "All of them asked for the same thing. A child. And you are here for the same thing," Artemis didn't ask a question but Poseidon nodded anyway. Artemis motioned for them to take a seat in front of the offerings. "These were offered to me by the magical couple. The husband, James Potter, was hit by a curse. He survived but it rendered him infertile. They have tried everything they could in both the magical and mortal worlds. Praying to me, that was their last hope," Artemis explained to them. The mood was somber as the two males took in the news.

"What will you do?" Poseidon asked studying his niece closely. Neither twin were afraid to admit the look on Poseidon's face scared them more than any monster ever could. But Artemis held his gaze without flinching.

"I am going to help them create a child. All four of them," Artemis spoke, turning to look at her twin when she said the last part. He understood what she hadn't said and smiled gently.

"We haven't done something like that in centuries," Apollo remineced.

"Done what?" Poseidon asked. Artemis and Apollo looked at their uncle with matching soft smiles. It was times like this (however few they were) that you could see the evidence they were twins.

"Create a child with four parents," the Sun God and Moon Goddess spoke together.

And chapter done! So yeah...this fic is going to be really weird. I noticed that the timelines for Harry Potter and Percy Jackson kinda fit together. The HP series always took place during the school years and the PJO took place during summers. That made me think it would be cool to do a Percy-is-Harry fic, and this was born. The fic chapters will get longer as the story progresses and I figure out how to plot. Sadly, the PJO elements won't tie in until after the chamber of secrets.

I hope you guys enjoy the fic! Please REVIEW! Reviews are amazing!
