~Amy's POV~

"Dan!" Amy Cahill yelled. "Give me back my book!"

"Not until you tell me where you hid my ninja suit!" Amy's thirteen-year-old brother, Dan, yelled back.

"I told you already! Nellie took it to the dry cleaners!" Nellie Gomez was their au pair and legal guardian, along with their Great Uncle Fiske.

"You're lying!" Dan retorted.

"No I'm not you dweeb!"

Amy was chasing Dan all around the mansion. As much as Amy hated to admit it – even with all of her training – Dan was still faster than her. She heard someone walk through the door.

"Kiddos! I'm home!" It was Nellie. "Dan, I forgot to tell you, I took your ninja outfit to the dry cleaners."

"Oops." Dan smiled apologetically towards Amy. "Here's your book?" It sounded more of a question than a statement.

She snatched it out of his hand.

I'm so going to kill you later, Amy's eyes told Dan's.

No! Please don't! I thought you were lying! Dan's eyes pleaded.

Sorry doesn't cut it.

Amy, it's just a book. Chill.

Amy glared at Dan. He walked into the kitchen to meet Nellie.

Amy's phone beeped. She looked at it. It was a text message from Fiske. It read:

I need just you and Dan to meet me at the Empire State Building today at 8:00 pm. Leave right away. This is very urgent.

Amy reread the message. She walked into the kitchen and showed the text to Dan and Nellie.

"Yes!" Dan exclaimed. "We're going to NYC, baby!"

Camp Half-Blood – Long Island; New York

~Percy's POV~

Percy Jackson was bored. He was at a camp counselor meeting in the big house. He rarely ever paid attention. The only good part was the free snacks on the table.

The counselors from the other cabins surrounded him. Percy was the head counselor for the Poseidon cabin. There was also Percy's girlfriend, Annabeth Chase, from the Athena cabin, Piper McLean from the Aphrodite cabin, Leo Valdez from the Hephaestus cabin, Thalia Grace representing both the Zeus and Artemis cabin, (it used to be Jason Grace, but after the war against the Giants', he returned to Camp Jupiter) Nico di Angelo from the Hades cabin, Clarisse la Rue from the Ares cabin, Connor and Travis Stoll from the Hermes cabin, Katie Gardner from the Demeter cabin, Will Solace from the Apollo cabin, and so on.

As Chiron was giving another lecture about cabin inspection, something interesting finally happened. An Iris Message appeared above the Ping Pong table.

"Chiron, this message is very urgent." A face appeared through the mist that Percy recognized as the king of the gods himself, Lord Zeus. "I need you to send Percy, Annabeth, Piper, Leo, Thalia, and Nico to Mount Olympus right away."

Before Chiron could respond, Zeus swiped his hand though the mist and cut the connection. For a moment, everyone was too stunned to say anything. No one moved an inch, which is saying something when you're in a room full of ADHD kids.

"I guess that means I have to send you guys to Mount Olympus as soon as possible." Chiron said, breaking the silence.

~Carter's POV~

"Carter!" Carter Kane's thirteen-year-old sister, Sadie, called to him.

"What?" Carter replied, irritated.

"Get over here!"

"Sheesh, I'm only standing five feet away. No need to yell!"

Sadie smirked. "Sorry, brother dear, but I am picking up signs of unexplainable magic at the Empire State Building."

"You sure? Because last time we went to investigate, the only things 'magical' that we found was the smell of tacos at a taco stand."

Sadie glared daggers at him. "Will you just forget about that already? This time, I'm sure of it."

"Fine. I'll go get Zia and Walt." Carter said.

He found them both in the library reading some ancient Egyptian scrolls.

"Guys, grab your wands and staffs." He explained. "We're going to the Empire State Building."
