So this is taking place in the year 2029. The 7 minus Hazel are around 35-36. Hazel and Nico are 32.

Percy, Annabeth, and their two twin 5 year old kids, Luke and Sally, were sitting at their dining room table eating in their New York apartment when they heard the phone ring. Annabeth rose from her chair and walks over to the receiver.

"Hello?" She ask after picking it up.

Percy looks over to ask who it is when Annabeth's face lights up. "Chiron, it's so nice to hear from you. How are you?"

Percy can't hear anything he's saying, so he proceeds to continue to eat. Annabeth continues to talk as Percy talks with their kids. He was actually trying to get them to eat their food. He thought it was because it wasn't blue, because blue food was the best. He was bribing them with ice cream for dessert when Annabeth walked back to the table.

"You kids can be finished, but no dessert tonight." Annabeth said before glancing at Percy. "And I have some news for you."

For a second he was worried something was wrong, but Annabeth's figure was relaxed. The kids quickly ran to their rooms before their parents changed their minds.

"What's wrong?" Percy asked, waiting for the worst. He hoped there were no apocalypses to take care of. He was done with those.

Annabeth smiled and shook her head. "Nothing, but Chiron did ask us something. Apparently there's a concert soon and he wants us to go. He didn't say why we have to go or who is playing there, but he said it's important. He asked the others to go to, and they all said yes. Though it's just for us, not the kids, so we'll have to have your mom watch the kids."

This made Percy curious. He wanted to know why Chiron wanted them to go see some concert. The 7 all lived in New York, and they saw each other often. "Sounds cool, when is it?"

"Tomorrow. I don't know why it's on such short notice. But one good thing is we got tickets near the front, so we'll be up close." Annabeth explained, picking up the plates and taking them to the kitchen.

Percy went to get his kids to bed, thinking of what would happen tomorrow. He had a feeling something big would happen, he just didn't know what.

Jason, Piper, and their son Jack were watching a movie when they got the call. Chiron told Jason the same thing he told Annabeth before hanging up.

"Who was that?" Piper asked.

Jason sat down on the couch and put his arm around Piper. "Apparently we're going to a concert tomorrow. Percy, Annabeth, Hazel, Frank, and Leo are going too. We're gonna have to find a babysitter for Jack."

"What about Calypso?" Piper asked. She and Leo were inseparable, so it was strange that he would go without her.

"She's staying home with Esperanza." Jason explained. "Leo almost wasn't going to go because of that, but she convinced his that she would be fine alone for a few hours."

Piper chuckled. "We'll I can't wait. I'll call the babysitter."

Frank and Hazel got the same call, but were more reluctant. Their 5 year old sun Sam and 2 year old daughter Emily had never had a babysitter before, and the worried parents weren't sure how the kids would react. But after a call to Percy, who convinced them to go, they asked their neighbor who they knew the children liked to be around to watch them. Luckily, she said yes, and it was settled.

Leo was extremely hard to convince. He was convinced something would go wrong if he left his wife and 10 month old daughter alone.

"What if a robber tries to break in?" He argued.

Calypso sighed and shook her head. "Leo, I know how to defend myself and Esperanza. Chiron wants us to go, so the least you can do is go for both of us."

Leo looked like he would argue more, but the look on Calypso's face told him it was useless.

"Fine," he said, throwing his hands in the air.

Calypso smiled. She knew he secretly wanted to go, but didn't want to admit it. Sometimes he's too stubborn for his own good.

Meanwhile, back at Camp Half-Blood, Chiron was smiling triumphantly to himself. The adult demigods had no idea what was in store for tomorrow. He had wondered if it was a good idea sending them, then dismissed it. This may be his only chance, and he wasn't going to waste it. He couldn't wait till tomorrow, knowing there would be phone calls to him asking if it had been his plan.
