Once the smoke cleared, I saw we had skidded to a stop on the old farm road just outside of camp. To our left loomed Half-Blood Hill, a single great pine tree rising from its summit, the Golden Fleece glittering from the lowest branch. Coiled around the base of the tree was Peleus the dragon. And standing next to the dragon, casually scratching its ears, was an old frenemy of mine: Dionysus, the god of doing things to annoy Apollo.

PERHAPS THAT LAST COMMENT WAS UNFAIR.

Dionysus was the god of other things, such as wine, madness, Oscar-night after-parties, and certain types of vegetation. But to me, he would always be the annoying little brother who followed me around, trying to get my attention by imitating everything I did.

You know the type. You’re a god. Your little brother pesters Dad to make him a god, too, even though being a god is supposed to be your thing. You have a nice chariot pulled by fiery horses. Your little brother insists on getting his own chariot pulled by leopards. You lay waste to the Greek armies at Troy. Your little brother decides to invade India. Pretty typical stuff.

Dionysus stood at the top of the hill, as if he’d been expecting us. Being a god, maybe he had. His leopard-skin golf shirt matched the Golden Fleece in the branch above him quite well. His mauve golf slacks did not. In the old days, I might have teased him about his taste in clothes. Now, I couldn’t risk it.

A lump formed in my throat. I was already carsick from our taxi ride and our impromptu game of catch-the-eyeball. My wounded forehead throbbed. My brain swirled with the new lines of prophecy the Gray Sisters had given us. I didn’t need any more things to worry about. But seeing Dionysus again…This would be complicated.

Meg slammed the taxi door behind her. “Thanks, guys!” she told the Gray Sisters. “Next time, tell me about the dog!”

Without so much as a good-bye or a plea to share their poetry with my literary agent, the Gray Sisters submerged in a pool of red-black tar.

Meg squinted up at the hill’s summit. “Who’s that guy? We didn’t meet him before.” She sounded suspicious, as if he were intruding on her territory.

“That,” I said, “is the god Dionysus.”

Meg frowned. “Why?”

She might have meant Why is he a god? Why is he standing up there? or Why is this our life? All three questions were equally valid.

“I don’t know,” I said. “Let’s find out.”

Trekking up the hill, I fought the urge to burst into hysterical sobbing or laughter. Probably I was going into shock. It had been a rough day, and it wasn’t even lunchtime yet. However, given the fact that we were approaching the god of madness, I had to consider the more serious possibility that I was having a psychotic or manic break.

I already felt disconnected from reality. I couldn’t concentrate. I didn’t know who I was, who I was supposed to be, or even who I wanted to be. I was getting emotional whiplash from my exhilarating surges of godlike power, my depressing crashes back into mortal frailty, and my adrenaline-charged bouts of terror. In such a condition, approaching Dionysus was asking for trouble. Just being near him could widen the cracks in anyone’s psyche.

Meg and I reached the summit. Peleus welcomed us with a puff of steam from his nostrils. Meg gave the dragon a hug around the neck, which I’m not sure I would have recommended. Dragons are notoriously not huggers.

Dionysus eyed me with a mixture of shock and horror, much the same way I looked at myself in the mirror these days.

“So, it’s true, what Father did to you,” he said. “That cold-hearted glámon.”

In Ancient Greek, glámon meant something like dirty old man. Given Zeus’s romantic track record, I doubted he would even consider it an insult.

Dionysus gripped my shoulders.

I didn’t trust myself to speak.

He looked the same as he had for the past half century: a short middle-aged man with a potbelly, sagging jowls, a red nose, and curly black hair. The violet tint of his irises was the only indicator that he might be more than human.

Other Olympians could never comprehend why Dionysus chose this form when he could look like anything he wanted. In ancient times, he’d been famous for his youthful beauty that defied gender.

But I understood. For the crime of chasing the wrong nymph (translation: one our father wanted instead), Dionysus had been sentenced to run this camp for a hundred years. He had been denied wine, his most noble creation, and forbidden access to Olympus except for special meeting days.

In retaliation, Dionysus had decided to look and act as ungodly as possible. He was like a child refusing to tuck in his shirt, comb his hair, or brush his teeth, just to show his parents how little he cared.

“Poor, poor Apollo.” He hugged me. His hair smelled faintly of grape-flavored bubble gum.

This unexpected show of sympathy brought me close to tears…until Dionysus pulled away, held me at arm’s length, and gave me a triumphant smirk.

“Now you understand how miserable I’ve been,” he said. “Finally, someone got punished even more harshly than me!”

I nodded, swallowing back a sob. Here was the old, on-brand Dionysus I knew and didn’t exactly love. “Yes. Hello, Brother. This is Meg—”

“Don’t care.” Dionysus’s eyes remained fixed on me, his tone infused with joy.

“Hmph.” Meg crossed her arms. “Where’s Chiron? I liked him better.”

“Who?” Dionysus said. “Oh, him. Long story. Let’s get you into camp, Apollo. I can’t wait to show you off to the demigods. You look horrible!”

We took the long way through camp. Dionysus seemed determined to make sure everyone saw me.

“This is Mr. A,” he told all the newcomers we encountered. “He’s my assistant. If you have any complaints or problems—toilets backing up or whatnot—talk to him.”

“Could you not?” I muttered.

Dionysus smiled. “If I am Mr. D, you can be Mr. A.”

“He’s Lester,” Meg complained. “And he’s my assistant.”

Dionysus ignored her. “Oh, look, another batch of first-year campers! Let’s go introduce you.”

My legs were wobbly. My head ached. I needed lunch, rest, antibiotics, and a new identity, not necessarily in that order. But we trudged on.

The camp was busier than it had been the winter when Meg and I first straggled in. Then, only a core group of year-rounders had been present. Now, waves of newly discovered demigods were arriving for the summer—dozens of dazed kids from all over the world, many still accompanied by the satyrs who had located them. Some demigods, who, evidently, had recently fought off monsters, were injured even worse than I was, which I suppose is why Meg and I didn’t get more stares.

We made our way through the camp’s central green. Around its edges, most of the twenty cabins buzzed with activity. Senior counselors stood in the doorways, welcoming new members or providing directions. At the Hermes cabin, Julia Feingold looked especially overwhelmed, trying to find temporary spots for all the campers still unclaimed by their godly parents. At the Ares cabin, Sherman Yang barked at anyone who got too close to the building, warning them to look out for the land mines around the perimeter. Whether or not that was a joke, no one seemed anxious to find out. Young Harley from the Hephaestus cabin dashed around with a huge grin on his face, challenging the newbies to arm-wrestling contests.
