Grover was having a snack in the living room. He was dressed for battle in an armored shirt made from tree bark and twist ties, with his wooden cudgel and his reed pipes hanging from his belt.
The Demeter cabin had whipped up a whole buffet in the hotel kitchens—everything from pizza to pineapple ice cream. Unfortunately, Grover was eating the furniture. He'd already chewed the stuffing off a fancy chair and was now gnawing the armrest.
"Dude," I said, "we're only borrowing this place."
"Blah-ha-ha!" He had stuffing all over his face. "Sorry, Percy. It's just . . . Louis the Sixteenth furniture. Delicious. Plus I always eat furniture when I get—"
"When you get nervous," I said. "Yeah, I know. So what's up?"
He clopped on his hooves. "I heard about Annabeth. Is she . . .?"
"She's going to be fine. She's resting."
Grover took a deep breath. "That's good. I've mobilized most of the nature spirits in the city—well, the ones that will listen to me, anyway." He rubbed his forehead. "I had no idea acorns could hurt so much. Anyway, we're helping out as much as we can."
He told me about the skirmishes they'd seen. Mostly they'd been covering uptown, where we didn't have enough demigods. Hellhounds had appeared in all sorts of places, shadow-traveling inside our lines, and the dryads and satyrs had been fighting them off. A young dragon had appeared in Harlem, and a dozen wood nymphs died before the monster was finally defeated.
As Grover talked, Thalia entered the room with two of her lieutenants. She nodded to me grimly, went outside to check on Annabeth, and came back in. She listened while Grover completed his report—the details getting worse and worse.
"We lost twenty satyrs against some giants at Fort Washington," he said, his voice trembling. "Almost half my kinsmen. River spirits drowned the giants in the end, but . . ."
Thalia shouldered her bow. "Percy, Kronos's forces are still gathering at every bridge and tunnel. And Kronos isn't the only Titan. One of my Hunters spotted a huge man in golden armor mustering an army on the Jersey shore. I'm not sure who he is, but he radiates power like only a Titan or god."
I remembered the golden Titan from my dream—the one on Mount Othrys who erupted into flames.
"Great," I said. "Any good news?"
Thalia shrugged. "We've sealed off the subway tunnels into Manhattan. My best trappers took care of it. Also, it seems like the enemy is waiting for tonight to attack. I think Luke"—she caught herself—"I mean Kronos needs time to regenerate after each fight. He's still not comfortable with his new form. It's taking a lot of his power to slow time around the city."
Grover nodded. "Most of his forces are more powerful at night, too. But they'll be back after sundown."
I tried to think clearly. "Okay. Any word from the gods?"
Thalia shook her head. "I know Lady Artemis would be here if she could. Athena, too. But Zeus has ordered them to stay at his side. The last I heard, Typhon was destroying the Ohio River valley. He should reach the Appalachian Mountains by midday."
"So at best," I said, "we've got another two days before he arrives."
Jake Mason cleared his throat. He'd been standing there so silently I'd almost forgotten he was in the room.
"Percy, something else," he said. "The way Kronos showed up at the Williamsburg Bridge, like he knew you were going there. And he shifted his forces to our weakest points. As soon as we deployed, he changed tactics. He barely touched the Lincoln Tunnel, where the Hunters were strong. He went for our weakest spots, like he knew."
"Like he had inside information," I said. "The spy."
"What spy?" Thalia demanded.
I told her about the silver charm Kronos had shown me, the communication device.
"That's bad," she said. "Very bad."
"It could be anyone," Jake said. "We were all standing there when Percy gave the orders."
"But what can we do?" Grover asked. "Frisk every demigod until we find a scythe charm?"
They all looked at me, waiting for a decision. I couldn't afford to show how panicked I felt, even if things seemed hopeless.
"We keep fighting," I said. "We can't obsess about this spy. If we're suspicious of each other, we'll just tear ourselves apart. You guys were awesome last night. I couldn't ask for a braver army. Let's set up a rotation for the watches. Rest up while you can. We've got a long night ahead of us."
The demigods mumbled agreement. They went their separate ways to sleep or eat or repair their weapons.
"Percy, you too," Thalia said. "We'll keep an eye on things. Go lie down. We need you in good shape for tonight."
I didn't argue too hard. I found the nearest bedroom and crashed on the canopied bed. I thought I was too wired to sleep, but my eyes closed almost immediately.
In my dream, I saw Nico di Angelo alone in the gardens of Hades. He'd just dug a hole in one of Persephone's flower beds, which I didn't figure would make the queen very happy.
He poured a goblet of wine into the hole and began to chant. "Let the dead taste again. Let them rise and take this offering. Maria di Angelo, show yourself!"
White smoke gathered. A human figure formed, but it wasn't Nico's mother. It was a girl with dark hair, olive skin, and the silvery clothes of a Hunter.
"Bianca," Nico said. "But—"
Don't summon our mother, Nico, she warned. She is the one spirit you are forbidden to see.
"Why?" he demanded. "What's our father hiding?"
