IT WAS ALL HARLEY’S FAULT.

After addressing the disappearance of Miranda Gardiner—“As a precautionary measure, please stay away from the woods until we know more”—Chiron called forward the young son of Hephaestus to explain how the three-legged death race would work. It quickly became apparent that Harley had masterminded the whole project. And, really, the idea was so horrifying, it could only have sprung from the mind of an eight-year-old boy.

I confess I lost track of the specifics after he explained the exploding chain-saw Frisbees.

“And they’ll be like, ZOOM!” He bounced up and down with excitement. “And then BUZZ! And POW!” He pantomimed all sorts of chaos with his hands. “You have to be really quick or you’ll die, and it’s awesome!”

The other campers grumbled and shifted on their benches.

Chiron raised his hand for silence. “Now, I know there were problems last time,” he said, “but fortunately our healers in the Apollo cabin were able to reattach Paolo’s arms.”

At a table in back, a muscular teen boy rose and began ranting in what I thought was Portuguese. He wore a white tank top over his dark chest, and I could see faint white scars around the tops of his biceps. Cursing rapidly, he pointed at Harley, the Apollo cabin, and pretty much everyone else.

“Ah, thank you, Paolo,” Chiron said, clearly baffled. “I’m glad you are feeling better.”

Austin leaned toward me and whispered, “Paolo understands English okay, but he only speaks Portuguese. At least, that’s what he claims. None of us can understand a word he says.”

I didn’t understand Portuguese either. Athena had been lecturing us for years about how Mount Olympus might migrate to Brazil someday, and we should all be prepared for the possibility. She’d even bought the gods Berlitz Portuguese DVDs for Saturnalia presents, but what does Athena know?

“Paolo seems agitated,” I noted.

Will shrugged. “He’s lucky he’s a fast healer—son of Hebe, goddess of youth, and all that.”

“You’re staring,” Nico noted.

“I am not,” Will said. “I am merely assessing how well Paolo’s arms are functioning after surgery.”

“Hmph.”

Paolo finally sat down. Chiron went through a long list of other injuries they had experienced during the first three-legged death race, all of which he hoped to avoid this time: second-degree burns, burst eardrums, a pulled groin, and two cases of chronic Irish step dancing.

The lone demigod at the Athena table raised his hand. “Chiron, just going to throw this out there….We’ve had three campers disappear. Is it really wise to be running a dangerous obstacle course?”

Chiron gave him a pained smile. “An excellent question, Malcolm, but this course will not take you into the woods, which we believe is the most hazardous area. The satyrs, dryads, and I will continue to investigate the disappearances. We will not rest until our missing campers are found. In the meantime, however, this three-legged race can foster important team-building skills. It also expands our understanding of the Labyrinth.”

The word smacked me in the face like Ares’s body odor. I turned to Austin. “The Labyrinth? As in Daedalus’s Labyrinth?”

Austin nodded, his fingers worrying the ceramic camp beads around his neck. I had a sudden memory of his mother, Latricia—the way she used to fiddle with her cowry necklace when she lectured at Oberlin. Even I learned things from Latricia Lake’s music theory class, though I had found her distractingly beautiful.

“During the war with Gaea,” Austin said, “the maze reopened. We’ve been trying to map it ever since.”

“That’s impossible,” I said. “Also insane. The Labyrinth is a malevolent sentient creation! It can’t be mapped or trusted.”

As usual, I could only draw on random bits and pieces of my memories, but I was fairly certain I spoke the truth. I remembered Daedalus. Back in the old days, the king of Crete had ordered him to build a maze to contain the monstrous Minotaur. But, oh no, a simple maze wasn’t good enough for a brilliant inventor like Daedalus. He had to make his Labyrinth self-aware and self-expanding. Over the centuries, it had honeycombed under the planet’s surface like an invasive root system.

Stupid brilliant inventors.

“It’s different now,” Austin told me. “Since Daedalus died…I don’t know. It’s hard to describe. Doesn’t feel so evil. Not quite as deadly.”

“Oh, that’s hugely reassuring. So of course you decided to do three-legged races through it.”
