The Red Pyramid (Kane Chronicles #1)(57)

“Carter,” Sadie said. “When the Rosetta Stone shattered, it let out five gods, right? Dad joined with Osiris. Amos told us that. Set...I don’t know. He got away somehow. But you and I—”

“The amulets protected us.” I clutched the Eye of Horus around my neck. “Dad said they would.”

“If we had stayed out of the room, as Dad told us to,” Sadie recalled. “But we were there, watching. We wanted to help him. We practically asked for power, Carter.”

Bast nodded. “That makes all the difference. An invitation.”

“And since then...” Sadie looked at me tentatively, almost daring me to make fun of her. “I’ve had this feeling. Like a voice inside me....”

By now the cold rain had soaked right through my clothes. If Sadie hadn’t said something, maybe I could’ve denied what was happening a little longer. But I thought about what Amos had said about our family having a long history with the gods. I thought about what Zia had told us about our lineage: “The gods choose their hosts carefully. They always prefer the blood of the pharaohs.”

“Okay,” I admitted. “I’ve been hearing a voice too. So either we’re both going crazy—”

“The amulet.” Sadie pulled it from her shirt collar and held it for Bast to see. “It’s the symbol of a goddess, isn’t it?”

I hadn’t seen her amulet in a long time. It was different from mine. It reminded me of an ankh, or maybe some kind of fancy tie.

“That is a tyet,” Bast said. “A magic knot. And yes, it is often called—”

“The Knot of Isis,” Sadie said. I didn’t see how she could know that, but she looked absolutely certain. “In the Hall of Ages, I saw an image of Isis, and then I was Isis, trying to get away from Set, and—oh, god. That’s it, isn’t it? I’m her.”

She grabbed her shirt like she physically wanted to pull the goddess away from her. All I could do was stare. My sister, with her ratty red-highlighted hair and her linen pajamas and her combat boots—how could she possibly worry about being possessed by a goddess? What goddess would want her, except maybe the goddess of chewing gum?

But then...I’d been hearing a voice inside me too. A voice that was definitely not mine. I looked at my amulet, the Eye of Horus. I thought about the myths I knew—how Horus, the son of Osiris, had to avenge his father by defeating Set. And at Luxor I’d summoned an avatar with the head of a falcon.

I was afraid to try it, but I thought: Horus?

Well, it’s about time, the other voice said. Hello, Carter.

“Oh, no,” I said, panic rising in my chest. “No, no, no. Somebody get a can opener. I’ve got a god stuck in my head.”

Bast’s eyes lit up. “You communicated with Horus directly? That’s excellent progress!”

“Progress?” I banged my palms against my head. “Get him out!”

Calm down, Horus said.

“Don’t tell me to calm down!”

Bast frowned. “I didn’t.”

“Talking to him!” I pointed at my forehead.

“This is awful,” Sadie wailed. “How do I get rid of her?”

Bast sniffed. “First off, Sadie, you don’t have all of her. Gods are very powerful. We can exist in many places at once. But yes, part of Isis’s spirit now resides inside you. Just as Carter now carries the spirit of Horus. And frankly, you both should feel honored.”

“Right, very honored,” I said. “Always wanted to be possessed!”

Bast rolled her eyes. “Please, Carter, it’s not possession. Besides, you and Horus want the same thing—to defeat Set, just as Horus did millennia ago, when Set first killed Osiris. If you don’t, your father is doomed, and Set will become king of the earth.”

I glanced at Sadie, but she was no help. She ripped the amulet off her neck and threw it down. “Isis got in through the amulet, didn’t she? Well, I’ll just—”

“I really wouldn’t do that,” Bast warned.

But Sadie pulled out her wand and smashed the amulet. Blue sparks shot up from the ivory boomerang. Sadie yelped and dropped her wand, which was now smoking. Her hand was covered in black scorch marks. The amulet was fine. “Ow!” she said.

Bast sighed. She put her hand on Sadie’s, and the burn marks faded. “I did tell you. Isis channeled her power through the amulet, yes, but she’s not there now. She’s in you. And even so, magical amulets are practically indestructible.”

“So what are we supposed to do?” Sadie said.

“Well, for starters,” Bast said, “Carter must use the power of Horus to defeat Set.”

“Oh, is that all?” I said. “All by myself?”

“No, no. Sadie can help.”

“Oh, super.”

“I’ll guide you as much as possible,” Bast promised, “but in the end, the two of you must fight. Only Horus and Isis can defeat Set and avenge the death of Osiris. That’s the way it was before. That’s the way it must be now.”

“Then we get our dad back?” I asked.

Bast’s smile wavered. “If all goes well.”

She wasn’t telling us everything. No surprise. But my brain was too fuzzy to figure out what I was missing.
