A/N: Thank you so much xXMoonylightXx for your support. Decided to continue the story for you! FYI: just got told that my website is going on to the next stage for History Fair. Wish me luck! Need to edit some things for it so I might delay posting. Here's the next chapter to amuse you till I can post the next one.

Annabeth:

We demigods sat quietly, processing the information. It wasn't hard to believe that there were wizards, since we were myths as well. What really puzzled me was why a mortal was involved. But, that wasn't very important. Protecting Harry and his friends was.

"Come on Ava, you can come help me pack," I said to the still quiet mortal who looked extremely out of place. Ava gave a quick nod, looking very grateful and awkward. I quickly gave Percy a peck on the lips before leading Ava outside and to my cabin.

"So Ava. How do you know about their and our adventures?" I asked curiously, hoping to learn a little more about this quest.

"Um. This is going to sound strange," Ava mumbled, not meeting my eyes. "I actually read about them for fun."

"What?" I replied. I'd never thought that our stories would be accessed by mortals.

"A man, Rick Riordan, wrote all about Percy's and your adventures. At home, your stories are featured in novels that are believed to be fictional. Now I know they're real," Ava said, not once looking up from the ground.

"Oh. Well. At least you're not coming in blind then," I said cautiously as we quickly went into my cabin so I can pack. I grabbed my suitcase and packed T-shirts, jeans, shorts, and everything I would need. Ava, surprisingly, knew where my bunk was and grabbed my laptop and Yankee's cap for me without prompting. "Ready?" I said after I zipped up my suitcase.

"Ready. Let's see how we're going to London," Ava replied cheerfully before leading the way back to the Big House. Maybe she wouldn't be such a bad guide after all.

Piper:

Jason, Leo, Percy, Frank, Hazel, Thalia, Nico, and I all left shortly after Annabeth to go pack. In about a half hour, all of us were done and ready to go. Ava, the mortal, stood off to the side, not sure what she should do. I exchanged a look with Hazel before we made our way over to her.

"Hi. I'm Piper and this is Hazel," I said cheerfully as I put out my hand.

"Ava Crowley. Pleasure to meet you," Ava said politely.

"So, Ava, where exactly is this school?" Hazel asked curiously.

"Um. In London. Problem is: the year that we are going to took place 18 years ago," Ava said calmly.

"18 years ago?" Leo said, listening in on our conversation. "In case you didn't realize, we really can't go back in time."

"Actually, I did last year. So it's possible," Ava replied confidently before turning back to look at Hazel and I. Suddenly, a bright white explosion happened a few feet away from us. When the smoke cleared, we saw Hecate standing royally.

"Lady Hecate. Welcome," Ava said calmly as the rest of us stood frozen.

"Miss Crowley, a pleasure," Hecate said warmly before making a clock appear in her hand. "Let's see, you need to be in 1996, am I correct?" Ava nodded her head as Hecate turned the hands back, causing the world to spin. After several moments, the spinning stopped and we noticed that we were not at camp anymore. In fact, everything looked completely unusual. Ava seemed to be the only one comfortable with this change.

"Alright everyone. Lady Hecate was gracious enough to not only take us to the right time, but to the right place. This is Little Whinging, Surrey."

Ava:

I couldn't believe that I was in Little Whinging, home of Harry Potter. Going to Hogwarts was one thing, but now traveling with my favorite demigods to a famous HP spot was unreal. Now, I realized, I had to act as a guide to the demigods so that they can help out Harry, Ron, and Hermione.

"Hold up," Thalia said sharply, drawing me out of my thoughts. "How is it that you know everything? Where we are, what we have done. Who exactly are you?" I drew in a sharp breath, unsure how to answer. I mean, I really didn't know anything. I didn't even know why I was even there myself. Luckily, at that moment, Harry, Dudley, and Mrs. Figg came walking down the road toward us.

"Ava?" Harry questioned as he approached closer toward the demigods and I.

"Hey Harry. Need help with Dudley?" I said as I walked over and to help him carry Dudley when Jason, Frank, and Percy all beat me to him. Harry gratefully handed his cousin to complete strangers before raced to me and hugging me. I felt like I was going to faint.

"I thought you said you weren't coming back?" Harry said happily, glad that that was a lie.

"I didn't think I was going to. Dumbledore sent me another ticket," I explained as I heard a grunt behind me. Oops. I completely forgot about the Heroes of Olympus. "Um. This is Percy Jackson, Annabeth Chase, and well, they should probably introduce themselves," I said as I turned and looked at the heroes. After a few moments, they all introduced themselves as Mrs. Figg came up to me and pulled me aside.

"You must be the one Dumbledore told be to look for. Come to my house as soon as you help take Dudley back to his parents," she whispered before walking away.

"What was that about?" Hazel asked me, overhearing it.

"We need to go to her house after we quickly help Harry," I replied quickly before rushing back to Harry's side. "Are you okay? I know about the dementors and their effect on you," I asked softly. Harry looked shocked that I knew before he remembered that I wasn't from his time. He nodded as we reached the Dursley's house. Harry thanked Frank, Jason, and Percy as he took his cousin and went inside the house.

"Percy, Annabeth, Jason, Piper, Frank, Hazel, Leo, Thalia, and Nico, I know you all what an explanation, but, honestly, I really can't give you one. Annabeth knows as much as me on this. All I know is that your adventures were written down in novels that I read. Yours as well as Harry's. However, I do not know how we play into his story so I'm as blind as you are about this quest. I traveled back to Harry's school last year to help him during the last task of the TriWizard Tournament when Lord Voldemort rose again. I know that I'm supposed to be your guide or whatever, but I really don't know what that means. I guess I just lead you through the wizarding world or something. Now though, I know what the next part in the plot, or story, or whatever is. We need to go to Mrs. Figg's house to travel to Grimmauld Place, the headquarters for the Order of the Pheonix," I finished, out of breath.

"Okay Ava. Lead the way then. We've got your back," Jason said warmly as he exchanged a look with Piper who nodded. Gratitude filled my heart as I smiled at the daughter of Aphrodite, feeling as if I made a friend. I took a deep breath and walked across the street with nine demigods following close behind.
