Hello! I'm so excited about writing this story! So here you go!
I don't own The 39 Clues, Percy Jackson and the Olympians, or The Kane Chronicles, Rick Riordan does.

Amy Cahill shivered as she walked home from her school. The bitter Boston weather was cooler than usual, but Amy was used to it. She enjoyed the cold, but even more, she enjoyed just being back in Boston. The clue hunt had only ended a few months ago, but to Amy, it only felt like a couple of weeks.

She turned the corner and approached the apartment building she, Dan, and Nellie were living at. As she walked closer to the door, she reached into her pocket for the key. It wasn't in there. Panic clouded her brain. The key! Where is the key!

"Hey, Amy!" a voice called out. Amy frowned and looked up. Dan was in the fire escape above her with her keys hanging from his fingers. She frowned.

"Dan! Drop me my keys!" she called. Dan pretended to yawn. Several violent thoughts entered Amy's head.

"Dan!" she snapped.

"I don't know, Amy," grinned Dan. "It's pretty cold out here. I feel like going back inside. Are you sure these keys are yours?" Dan held the keys out a little farther.

"I know where your samurai swords are Dan!" Amy threatened. Dan's eyes widened. He tossed her the keys and scrambled inside the window. Amy was grinning as she opened the door and walked inside. It was warm and she took off her coat. She heard Dan searching through his room, most likely looking for his swords.

She walked to her room, shut the door, dropped her backpack near her desk, and fell on her bed. After nine weeks of school, Amy and Dan finally had their Christmas break.

Amy felt her pocket vibrate. She reached inside and grabbed her phone. On the screen it said:

New Message From:
Fiske Cahill

Amy pressed the button to read the message.

Amy, the Madrigals need you and Dan in London. I know you two are on a school break, so I hope it will not be a problem. Meet me at Cleopatra's Needle in two days. I've booked your flight and hotel.
-Uncle Fiske

Amy frowned. The Madrigals needed their help? The clue hunt just ended. Amy was finally used to a normal life, not the life of hiding behind corners, betraying her family, and avoiding poisions, darts, and guns. Also, it was the holidays. Amy had half a mind to ignore the message.

But, she thought, we are Madrigal agents. We have to.

She heard the front door open and close.

"Hey, kiddos! I'm back!" Nellie's voice rang out. Amy pulled open her room door and walked out to meet Nellie in the kitchen.

"What's up, Amy," Nellie said while sorting through the groceries she brought. Amy shook her head as she told Nellie about Fiske's message.

"We need to go to London. Fiske said the Madrigals need us there," Nellie's head shot up.

"In London? We were just there!" she said in disbelief. Amy nodded.

"Fiske said he booked our flight and a hotel already. I think it would be important," Amy murmured. At that moment, Dan rushed in. His eyes were wide.

"We are going, aren't we?"


Percy watched his back as he, Annabeth, Grover, Rachel, Nico, and Thalia roamed the streets of London.

"Are you sure this is where Chiron wanted us to go?" Nico asked uncertainly.

"Yes! He sent me an IM! He told us to meet him at Cleopatra's Needle," Annabeth answered. Percy smiled his thanks, because something didn't feel right. He felt like they weren't supposed to be there.

"I agree with Nico," Rachel said. She earned herself a look of annoyance from Thalia.

"Of course we're supposed to be here! Even Artemis let me have some time away from the Hunters!" she almost yelled. "Also, you're just a mortal. How would you know what's right or wrong here?"

Rachel glared at Thalia, "I may be mortal, but I'm a very important mortal!"

"Yes, of course. The VIM of the year!" Thalia said as she threw her arms in the air. "Whoo-hoo!" Rachel's expression looked like she was mad at herself.

"Hey!" Grover said. "Don't draw too much attention! I smell something powerful nearby. It's nothing I've ever smelled before, but I'm positive it's not a monster."

"I'm not sure whether to cheer or to groan," Percy muttered. "It could be worse than a monster, or harmless, but then, I can't name anything in our lives that's ever been harmless."

"One second, Percy," Annabeth said. She looked around the group and broke into a grin. "We're close the Cleopatra's Needle now!" Annabeth started to run, leaving the others behind to catch up to her. She disappeared behind a corner and Percy began to get worried. If Annabeth was alone, any monster could get her. She shouldn't have ran off on her own!

"Annabeth!" Percy called. He rounded the corner with Nico, Thalia, Rachel, and Grover. They saw Annabeth gaping at an obelisk across the street. Percy knew they would have to deal with Annabeth's architecture obssession. He heard Annabeth whisper something that he thought was, "Oh my gods! This is amazing! If only I could go see the Great Pyramids of Giza!"

"Let's go, guys!" Thalia announced. "Chiron awaits!"

The six teens walked across the streets and towards the obelisk. Percy looked around for any sign of a man in a wheelchair. There wasn't any sign.

"Percy, I don't think this is a good idea. Something feels wrong! We aren't supposed to be here!" Nico said, his eyes filling with horror.

"One second! I'll Iris Message Chiron," Percy said as he took a drachma from his pocket. "Thalia, can you come with me? I need help with the Mist."

"Sure," Thalia shurgged. She followed Percy as he left the group in search of a puddle.

Percy found a puddle behind some pillars and hid himself from the sight of the mortals, "Thalia, if there's anyone looking, that's where I need you to mess with the Mist."

"I know, Kelp Head," Thalia said in a bored tone.

Percy willed the water from the puddle to rise into the air so that the moisture created a rainbow. He raised the drachma in front of him and said, "Iris, goddess of the rainbow, please accept my offering." He threw the golden coin into the rainbow and watched as it disapeared in it. "Chiron, Camp Half-Blood?" The last part was more of a question, since he wasn't sure where Chiron was. To his disappointment, Chiron appeared in the rainbow wearing a Party Ponies t-shirt and listening to the music that made Percy feel like his ears were bleeding.

"Percy? Where are you?"

"You told us to go to Cleopatra's Needle in London!" Chiron's face twisted in confusion.

"I did not, Percy. Wait, you're there? Right now?"

"Yeah! You told us to come!" Percy said, half in panic and half in frustration.

"Percy, you need to leave, now! I sense powerful forces there!"

"What? No, you-you said to come!" Thalia growled at the IM.

"Percy, Thalia, get the others and leave. Now-" the IM cut off. Percy was breathing hard. If Chiron hadn't told them to come, who did? He and Thalia turned around and ran to the others.

"We need to get away from here!" Percy told them. They only just understood what Percy was saying before they all blacked out. Percy was unconcious before he hit the ground.


"Carter, I can't believe you actually got me to come," Sadie grumbled. She looked out the window at the cars passing by. It was winter, almost Christmas. Just a year ago, Sadie lost her father. Now they were going back to Cleopatra's Needle. Back to the area where her mother died, burned up because of too powerful magic. Back to one of the last areas she spent with her father, when he was truly alive. Back to the last area where she didn't share her body with a god.

Carter didn't answer her. He was stroking Muffin's fur. Bast didn't know where they were going because she was in Muffin-form. If she knew Sadie and Carter were going to Cleopatra's Needle, they'd be chained up to their beds. She was snoring heavily in Carter's lap.

"Earth to Carter," Sadie said as she punched him in the arm. He flinched and Muffin woke up. Her eyes scanned the cab that they were in, then she looked outside the window. As soon as she did, her fur arched up and she hissed at Carter and Sadie.

"Great job, Sadie! What now?" Carter said, frustrated. Sadie glared at him and groaned.

"Magic, you idiot," she replied. "Hold her still." Carter frowned but tried to do as she said. Muffin was obviously not happy. She hissed and spat at Carter as he tried to hold her still. Sadie stayed quiet while she concentrated on her magic. She glanced at the driver, who was looking in the rear-view mirror at Carter and Muffin. Sadie smiled at him.

"Oh, the cat is just a little irritated. Don't worry," she said with a sweet smile. The driver shrugged and looked back at the road.

Carter finally pinned Muffin down and Sadie put her hand on the still furious cat. She whispered "Sleep" in Ancient Egyptian and waited for the spell to work on Muffin. She stopped struggling and her eyes started to close. Sadie and Carter let out a sigh of relief.

"Next time, think things through before you punch me," Carter said irritably. Sadie rolled her eyes and looked out the window. She was beginning to recognize the streets and knew they were getting closer to Cleoptra's Needle.

"Why did you want to come here, Carter?" Sadie asked. She remembered how suspicious she was of her father a year ago. The only day she had with her dad and he goes off to blow up one of the most famous Egyptian artifacts.

"Something tells me we have to come. It's not Horus. It's something else," he said, sounding a little spaced out. Sadie didn't know what Carter was talking about, but she was irritated that he didn't have a specific reason.

"So you dragged me to London because you felt like you needed to?" Sadie growled. Carter sent her a cautious glance.

"My ba took a trip a few days ago, Sadie. That hasn't happened since the last Demon Days," Carter defended. He glanced outside the window. "Driver, stop here."

The cab driver pulled over to the sidewalk and Carter rushed out. Sadie grabbed Muffin and followed him. She closed the door, turned to the driver's window and held out some money to pay him. The driver happily took the money and drove off.

"Well, let's go," Sadie told Carter.

"Yeah," Carter agreed. They made their way over to the giant obelisk across the street. Carter wasn't used to the busy streets of London and almost got run over by a car. They ran and Sadie laughed the entire way.

She stopped when she say a group of teens huddled in a group. They seemed to be arguing and two of the teens quickly hid behind a pillar nearby.

"Carter, those kids seem odd, don't you think? Look at them, they look really nervous," Sadie commented but when she looked at Carter, she saw that he was looking somewhere else.

"Those kids look suspicious, too," he said as he pointed to a group of three people, two kids and a lady who looked about twenty, walking towards the obelisk. She saw they had a silver spotted cat following close behind. Sadie was startled when the cat turned in their direction. It seemed to be staring right at them!

"You see that too, right?" asked Carter. He was looking at the cat. Sadie nodded.

"Yep, I sure do."

Sadie turned to look back at the group of teens. The two kids that left were running back to their friends. The look of terror on their faces was like seeing a beam of light in a darkened room. They talked rapidly before they all fell to the ground. To Sadie's shock, they faded right through the hard cement.

"Carter!" she gasped. He turned to look at the teens right as they disappeared completely.

"What?" he asked.

"You didn't see that? Those kids fainted and sank into the ground!" Sadie said. Carter looked at the area where the group was previously, then gave Sadie a confused look.

"I didn't see them. I was too busy looking at them," he pointed to the three people with the cat. The cat hadn't turned away and its owners didn't even notice. The lady looked like she had blond hair with various black streaks. Sadie reached up and stroked the streaks in her own hair. They were purple this time. The girl was about Carter's age and she had reddish-brown hair. The girl was nervously looking around and at the cell phone in her hand. Next to her was a younger boy who had dark blond hair. He was jumping around and his mouth was moving like he was talking non-stop.

Sadie noticed two figures following close behind. She wouldn't have noticed them if she wasn't being so observant. The two figures stayed hidden in the shadows, but they were definately following the girl, boy, and the lady.

"Carter, this is too wierd! There's someone following them!" she said. Carter frowned.

"Where? I don't see anyone," he replied.

Suddenly, every person around seemed to be following the three people. One was a large boy in a purple track suit. Nearby, there was three more people. Sadie couldn't see them well, but they were definately a girl and two identical boys. The two figures Sadie saw first were getting closer and they passed by an area where there was no shadows to hide them. It was a boy and a younger girl. They both had dark hair and coffee-colored skin. One last person was following them. It was another boy and he seemed familiar to Sadie. She tried to remember where she saw him. Television? Movies? Commercials? Maybe all of the above?

"They are so oblivious!" Sadie muttered. She moved forward to get those people out of trouble. Carter grabbed her arm and pulled her back.

"Wait! Look," he said.

The reddish-brown haired girl turned and it looked like she was greeting each person who seemed to be following them. Sadie frowned. She was getting paranoid. Well, maybe not. Those other teens had caused some suspision to spark. They had fainted right next to Cleopatra's Needle. This was obviously the work of Egyptian magic.

Muffin was still in Sadie's arms. She nearly dropped Muffin when she saw that she was glowing. Uh oh.

"Carter, we have to leave!" Sadie nudged her brother. He looked at Muffin and his eyes grew wide. Bast!

Sadie and Carter ran, but before they could go far, Sadie and Carter collapsed. Sadie's last thought was, We're so dead!


Dan looked around at the people gathering around him. Jonah Wizard was flinching everytime someone took a picture with their cameras. Dan knew he was trying not to draw attention. Hamilton Holt was grinning as he approached him, Amy and Nellie.

"Hey, dudes!" he greeted.

"Hey, Hammer!" Dan replied. They bumped knuckles. Ned, Ted, and Sinead joined the group, shortly followed by Ian and Natalie Kabra.

"Why are you blokes here?" Natalie said, her voice grim.

"Way to ruin the reunion, Natalie," Dan glared at her. She glared back and Dan imagined her old dart gun in her hand. Amy tried to keep them from fighting by answering Natalie's question.

"Fiske told us to come. We didn't know you were coming, too," she said.

"Yo, homies, I gotta know why I have to be here. My ol' man is gonna look for me if I'm gone too long," Jonah said, trying to stick to his gangter slang.

Amy glanced at Dan. They looked at each other. Why are they here? Amy's look said.

I don't know! How am I supposed to know? Dan's look said.

Amy looked back at the Starlings, Jonah, Hamilton, and the Kabras. Nellie stayed silent. Dan examined the Starlings. Sinead's scars weren't noticable anymore. Ned and Ted looked like they were trying their best to look normal, not like the twins that suffered from blindness and brain damage.

Ian and Natalie didn't look like they changed at all. They still wore designer clothes, shoes, and looked like kid models, but there was a nervous glint in their eyes that showed Dan that they were scared to be in London. He knew they were scared of their father, since their mother was in prison for killing Dan and Amy's parents.

Dan started to feel dizzy. He noticed the others looked pale and unfocused. He heard Amy's phone vibrate and saw she got a message from Uncle Fiske. He knew it was the reply from the message she sent him asking him where he was. He looked at the screen, trying not to pass out.

Amy,
I did not tell you to go to London. Are you there? If you are, you need to leave,
now. There is a Vesper sighting in London.

Dan almost choked. Vespers! He and Amy stared at each other wide-eyed before Dan fell face-first into the ground.
