“We only have a few hours, so listen carefully.If you’re hearing this story, you’re already in danger. Sadie and I might be your only chance.Go to the school. Find the locker. I won’t tell you which school or which locker, because if you’re the right person, you’ll find it. The combination is 13/32/33. By the time you finish listening, you’ll know what those numbers mean. Just remember the story we’re about to tell you isn’t complete yet. How it ends will depend on you.The most important thing: when you open the package and find what’s inside, don’t keep it longer than a week. Sure, it’ll be tempting. I mean, it will grant you almost unlimited power. But if you possess it too long, it will consume you. Learn its secrets quickly and pass it on. Hide it for the next person, the way Sadie and I did for you. Then be prepared for your life to get very interesting.”

“I tell aspiring writers that you have to find what you MUST write. When you find it, you will know, because the subject matter won’t let you go. It’s not enough to write simply because you think it would be neat to be published. You have to be compelled to write. If you’re not, nothing else that you do matters.”

“Hang on," Sadie said. She stomped right up to the throne. Ammit growled at her, but Sadie growled back, which confused the monster into silence. "What are you?" she demanded. "My dad? Osiris? Are you even alive?" Dad looked at Anubis. "What did I tell you about her? Fiercer than Ammit, I said." "You didn't need to tell me." Anubis's face was grave."I've learned to fear that sharp tongue." Sadie looked outraged. "excuse me?”

“Zia turned toward us, her expression grim. “I will show you to your quarters. In the morning, your testing begins. We will see what magic you know, and how you know it.”I wasn’t sure what she meant by that, but I exchanged an uneasy look with Sadie.“Sounds fun,” Sadie ventured. “And it we fail this test?”Zia regarded her coldly. “This is not the sort of test you fail, Sadie Kane. You pass or you die.”

“Leo,” Jason said, “you’re weird.”“Yeah, you tell me that a lot.” Leo grinned. “But if you don’t remember me, that means I can reuse all my old jokes...!”

“What are you?” She demanded. “My dad? Osiris? Are you even alive?”Dad looked at Anubis. “What did I tell you about her? Fiercer than Ammit, I said.”“You didn’t need to tell me that.” Anubis’s face was grave. “I’ve learned to fear that sharp tongue.”Sadie looked outraged. “Excuse me?”

“I've got a few ideas," (Amy) admitted. "But I don't know where we're going in the long term. I mean - have you ever thought about what this ultimate treasure could be?""Something cool." (Dan)"Oh, that's real helpful. I mean, what could make somebody the most powerful Cahill in history? And why thirty-nine clues?"Dan shrugged. "Thirty-nine is a sweet number. It's thirteen times three. It's also the sum of five prime numbers in a row - 3,5,7,11,13. And if you add the first three powers of three, 3 to the first, 3 to the second, and s to the third, you get thirty-nine."Amy stared at him. "How did you know that?""What do you mean? It's obvious.”
