The Daughter of Percy Jackson

Annie was trying to keep up on her chubby toddler legs. Annabeth was right on my heels the entire time. Selena was pretty snobby, but she was still a camper who didn't deserve to die.
"Grover!" I yelled to the goat-man running fifteen feet ahead of us. "What happened?!"
Grover started running backwards so he could look at me while talking.
"Selena was hit in the head by a... um... well, a kid." He turned back around, and started to go into a full sprint.
We got to the dining pavilion in five minutes, with the rest of the camp around a body.
We nudged our way into the circle, and there was a happy little toddler bouncing around on Selena's chest. She had black hair and dark green eyes.
"What the Hades?" Annabeth said, picking up the child. "Another one?" The entire camp was silent.
"Guys... The fleece! Go get the fleece!" She motioned to a group of campers, who, without hesitation, ran off in the direction of Thalia's tree.
"Great. So who's the parents of this one?" I asked, annoyed. I loved kids and all, but this was a bit much. Annie was a handful by herself, and another one wouldn't help.
"Daddy!" The girl said, running up to me and hugging my legs.
"Oh God's... Great!" I said with a smile, but on the inside, I was screaming. I held up the little girl. "So what's your name, huh? Got a name tag or receipt or something?" started looking the baby over, examining her armpits, sandals and shirt for any tags.
"It's me, daddy! Sadie!"
"And let me guess..." I said, pointing to Annabeth, who was blushing like crazy. "That's your mother?"
The toddler shook it's head. "That's Aunt Annie, silly! Why are you so small?" She poked my nose.
"Wait... That's your Aunt... than who's your mom?"
The toddler pointed to Selena.
"I... I don't understand... What?" I put the kid down and examined her. She looked like a small version of me, if I was a girl.
"You're silly, daddy!" She poked her deceased mom. "Wake up!"
Nico entered the pavilion. He obviously just woke up, his hair was a mess, and his clothes were wrinkled.
"What happened?" He asked, rubbing his head.
As he said that, the campers came back with the fleece. They layed it over Selena, and she started to turn gold. Selena died during the titan war. Grover, Annabeth and I all were able to have one wish. But Thalia also got a wish as well. Of course, this was after she was fixed up and everyone was back at camp. She wished that all of her close friends were reanimated into their bodies and given a second chance at life. This included Selena (Which surprised some people), Zoe, and Bianca. But of course, the other two had to go back to hunting with Artemis, and Selena had a great story to tell of the underworld. But now, Selena was killed again by her own son.
The fleece was healing her, but still. That's just a bit creepy.
"Daddy? Why are there two of you?" Sadie said, pointing to Nico and me.
"What do you mean?" I asked.
"There is two Nico's... Two daddies!" That explains it! Nico had a growth spurt, and I hadn't gotten a haircut since the kids arrived. Now that I think of it, we both look alike.
"Oh..." I sighed, and turned to Annabeth. "I knew I wouldn't cheat on you."

"So wait," Said a familiar, male voice. "Are we just going to forget about me, Beckendorf?"
