“Percy!” Thalia said. “This isn’t the time.”

But I couldn’t help staring at the two giant bronze guys with tall bladed wings like letter openers. They were weathered brown except for their toes, which shone like new pennies from all the times people had rubbed them for good luck.

Good luck. The blessing of Zeus.

I thought about the tour guide in the elevator. Her gray eyes and her smile. What had she said? There is always a way for those clever enough to find it.

“Thalia,” I said. “Pray to your dad.”

She glared at me. “He never answers.”

“Just this once,” I pleaded. “Ask for help. I think . . . I think the statues can give us some luck.”

Six skeletons raised their guns. The other five came forward with batons. Fifty feet away. Forty feet.

“Do it!” I yelled.

“No!” Thalia said. “He won’t answer me.”

“This time is different!”

“Who says?”

I hesitated. “Athena, I think.”

Thalia scowled like she was sure I’d gone crazy.

“Try it,” Grover pleaded.

Thalia closed her eyes. Her lips moved in a silent prayer. I put in my own prayer to Annabeth’s mom, hoping I was right that it had been her in that elevator—that she was trying to help us save her daughter.

And nothing happened.

The skeletons closed in. I raised Riptide to defend myself. Thalia held up her shield. Zoë pushed Grover behind her and aimed an arrow at a skeleton’s head.

A shadow fell over me. I thought maybe it was the shadow of death. Then I realized it was the shadow of an enormous wing. The skeletons looked up too late. A flash of bronze, and all five of the baton-wielders were swept aside.

The other skeletons opened fire. I raised my lion coat for protection, but I didn’t need it. The bronze angels stepped in front of us and folded their wings like shields. Bullets pinged off of them like rain off a corrugated roof. Both angels slashed outward, and the skeletons went flying across the road.

“Man, it feels good to stand up!” the first angel said. His voice sounded tinny and rusty, like he hadn’t had a drink since he’d been built.

“Will ya look at my toes?” the other said. “Holy Zeus, what were those tourists thinking?”

As stunned as I was by the angels, I was more concerned with the skeletons. A few of them were getting up again, reassembling, bony hands groping for their weapons.

“Trouble!” I said.

“Get us out of here!” Thalia yelled.

Both angels looked down at her. “Zeus’s kid?”

“Yes!”

“Could I get a please, Miss Zeus’s Kid?” an angel asked.

“Please!”

The angels looked at each other and shrugged.

“Could use a stretch,” one decided.

And the next thing I knew, one of them grabbed Thalia and me, the other grabbed Zoë and Grover, and we flew straight up, over the dam and the river, the skeleton warriors shrinking to tiny specks below us and the sound of gunfire echoing off the sides of the mountains.

I WRESTLE SANTA’S EVIL TWIN

“Tell me when it’s over,” Thalia said. Her eyes were shut tight. The statue was holding on to us so we couldn’t fall, but still Thalia clutched his arm like it was the most important thing in the world.

“Everything’s fine,” I promised.

“Are . . . are we very high?”

I looked down. Below us, a range of snowy mountains zipped by. I stretched out my foot and kicked snow off one of the peaks.

“Nah,” I said. “Not that high.”

“We are in the Sierras!” Zoë yelled. She and Grover were hanging from the arms of the other statue. “I have hunted here before. At this speed, we should be in San Francisco in a few hours.”

“Hey, hey, Frisco!” our angel said. “Yo, Chuck! We could visit those guys at the Mechanics Monument again! They know how to party!”

“Oh, man,” the other angel said. “I am so there!”

“You guys have visited San Francisco?” I asked.

“We automatons gotta have some fun once in a while, right?” our statue said. “Those mechanics took us over to the de Young Museum and introduced us to these marble lady statues, see. And—”

“Hank!” the other statue Chuck cut in. “They’re kids, man.”

“Oh, right.” If bronze statues could blush, I swear Hank did. “Back to flying.”

We sped up, so I could tell the angels were excited. The mountains fell away into hills, and then we were zipping along over farmland and towns and highways.

Grover played his pipes to pass the time. Zoë got bored and started shooting arrows at random billboards as we flew by. Every time she saw a Target department store—and we passed dozens of them—she would peg the store’s sign with a few bulls-eyes at a hundred miles an hour.

Thalia kept her eyes closed the whole way. She muttered to herself a lot, like she was praying.

“You did good back there,” I told her. “Zeus listened.”

It was hard to tell what she was thinking with her eyes closed.

“Maybe,” she said. “How did you get away from the skeletons in the generator room, anyway? You said they cornered you.”

I told her about the weird mortal girl, Rachel Elizabeth Dare, who seemed to be able to see right through the Mist. I thought Thalia was going to call me crazy, but she just nodded.

“Some mortals are like that,” she said. “Nobody knows why.”

Suddenly I flashed on something I’d never considered.

My mom was like that. She had seen the Minotaur on Half-Blood Hill and known exactly what it was. She hadn’t been surprised at all last year when I’d told her my friend Tyson was really a Cyclops. Maybe she’d known all along. No wonder she’d been so scared for me as I was growing up. She saw through the Mist even better than I did.

“Well, the girl was annoying,” I said. “But I’m glad I didn’t vaporize her. That would’ve been bad.”

Thalia nodded. “Must be nice to be a regular mortal.”

She said that as if she’d given it a lot of thought.

“Where you guys want to land?” Hank asked, waking me up from a nap.

I looked down and said, “Whoa.”

I’d seen San Francisco in pictures before, but never in real life. It was probably the most beautiful city I’d ever seen: kind of like a smaller, cleaner Manhattan, if Manhattan had been surrounded by green hills and fog. There was a huge bay and ships, islands and sailboats, and the Golden Gate Bridge sticking up out of the fog. I felt like I should take a picture or something. Greetings from Frisco. Haven’t Died Yet. Wish You Were Here.

“There,” Zoë suggested. “By the Embarcadero Building.”

“Good thinking,” Chuck said. “Me and Hank can blend in with the pigeons.”

We all looked at him.

“Kidding,” he said. “Sheesh, can’t statues have a sense of humor?”

As it turned out, there wasn’t much need to blend in. It was early morning and not many people were around. We freaked out a homeless guy on the ferry dock when we landed. He screamed when he saw Hank and Chuck and ran off yelling something about metal angels from Mars.

We said our good-byes to the angels, who flew off to party with their statue friends. That’s when I realized I had no idea what we were going to do next.

We’d made it to the West Coast. Artemis was here somewhere. Annabeth too, I hoped. But I had no idea how to find them, and tomorrow was the winter solstice. Nor did I have any clue what monster Artemis had been hunting. It was supposed to find us on the quest. It was supposed to “show the trail,” but it never had. Now we were stuck on the ferry dock with not much money, no friends, and no luck.

After a brief discussion, we agreed that we needed to figure out just what this mystery monster was.

“But how?” I asked.

“Nereus,” Grover said.

I looked at him. “What?”

“Isn’t that what Apollo told you to do? Find Nereus?”
