The Red Pyramid -1 by Rick Riordan

was a demon," Amos said. "A minion of chaos. And if demons are coming through to the mortal world, we don't have much time. This is bad, very bad."

    "If you live in Phoenix," I said.

    "Carter, our enemy won't stop in Phoenix. If he's grown so powerful so fast...What did he say about the storm, exactly?"

    "He said: 'I will summon the greatest storm ever known.'"

    Amos scowled. "The last time he said that, he created the Sahara. A storm that large could destroy North America, generating enough chaos energy to give him an almost invincible form."

    "What are you talking about? Who is this guy?"

    Amos waved away the question. "More important right now: why didn't you sleep with the headrest?"

    I shrugged. "It was uncomfortable." I looked at Sadie for support. "You didn't use it, did you?"

    Sadie rolled her eyes. "Well, of course I did. It was obviously there for a reason."

    Sometimes I really hate my sister. [Ow! That's my foot!]

    "Carter," Amos said, "sleep is dangerous. It's a doorway into the Duat."

    "Lovely," Sadie grumbled. "Another strange word."

    "Ah...yes, sorry," Amos said. "The Duat is the world of spirits and magic. It exists beneath the waking world like a vast ocean, with many layers and regions. We submerged just under its surface last night to reach New York, because travel through the Duat is much faster. Carter, your consciousness also passed through its shallowest currents as you slept, which is how you witnessed what happened in Phoenix. Fortunately, you survived that experience. But the deeper you go into the Duat, the more horrible things you encounter, and the more difficult it is to return. There are entire realms filled with demons, palaces where the gods exist in their pure forms, so powerful their mere presence would burn a human to ashes. There are prisons that hold beings of unspeakable evil, and some chasms so deep and chaotic that not even the gods dare explore them. Now that your powers are stirring, you must not sleep without protection, or you leave yourself open to attacks from the Duat or...unintended journeys through it. The headrest is enchanted, to keep your consciousness anchored to your body."

    "You mean I actually did..." My mouth tasted like metal. "Could he have killed me?"

    Amos's expression was grave. "The fact that your soul can travel like that means you are progressing faster than I thought. Faster than should be possible. If the Red Lord had noticed you--"

    "The Red Lord?" Sadie said. "That's the fiery bloke?"

    Amos rose. "I must find out more. We can't simply wait for him to find you. And if he releases the storm on his birthday, at the height of his powers--"

    "You mean you're going to Phoenix?" I could barely get the words out. "Amos, that fiery man defeated Dad like his magic was a joke! Now he's got demons, and he's getting stronger, and-you'll be killed!"

    Amos gave me a dry smile, like he'd already weighed the dangers and didn't need a reminder.
    His expression reminded me painfully of Dad's. "Don't count your uncle out so quickly, Carter.
    I've got some magic of my own. Besides, I must see what is happening for myself if we're to have any chance at saving your father and stopping the Red Lord. I'll be quick and careful. Just stay here. Muffin will guard you."

    I blinked. "The cat will guard us? You can't just leave us here! What about our training?"

    "When I return," Amos promised. "Don't worry, the mansion is protected. Just do not leave. Do not be tricked into opening the door for anyone. And whatever happens, do not go into the library. I absolutely forbid it. I will be back by sunset."

    Before we could protest, Amos walked calmly to the edge of the terrace and jumped.

    "No!" Sadie screamed. We ran to the railing and looked over. Below was a hundred-foot drop into the East River. There was no sign of Amos. He'd simply vanished.

    Philip of Macedonia splashed in his pool. Muffin jumped onto the railing and insisted we pet her.

    We were alone in a
