The Hermes cabin was exactly what it sounded like: the temporary home of every child who did not yet have a permanent one, plus the permanent home of Hermes's own children, which meant the cabin's character was shaped by the god of travelers and thieves and messengers — fluid, adaptable, slightly chaotic, and deeply, genuinely welcoming to newcomers in the way that people who have always been on the road are welcoming to other travelers.
Connor and Travis Stoll were thirteen and fourteen respectively, and they were exactly as described in his memory except more present — louder, quicker, and more immediately likable than any description captured. They introduced themselves by name and by immediate offer of the top bunk on the left side, which was 'the best bunk because it's near the window but not the drafty window,' and followed this with a comprehensive tour of the cabin that included the location of the good flashlights, the hiding spot for the extra snacks, and the drawer that stuck unless you lifted and pulled simultaneously.
'You're the weird double-bloodline kid,' Travis said, with the cheerful directness of someone for whom this was a compliment. 'Word gets around. Chiron told a few people you were coming.'
'Both Apollo and old magic stuff,' Connor added. 'That's unusual. Usually it's one or the other.'
'Both,' Kael confirmed. He was keeping his full description deliberately vague until the claiming clarified things publicly.
He was assigned a bunk and given the tour and folded into the cabin's evening routine with the easy, practiced hospitality of the Hermes cabin, which Kael thought was probably its best quality. It did not require you to belong to a specific divine parent. It simply required that you were here, and that was enough.
He lay in his bunk that first night and listened to the cabin's sounds settling into sleep around him and looked at the ceiling and thought: I am here. I am actually here.
He had been in this place in his imagination for eleven years. In memory — someone else's, filtered through five books. In his planning, in his coded notebooks, in the mental maps he had been building since he was four years old. He had thought about Camp Half-Blood more consistently and more deeply than he had thought about most real places he had actually been.
And here it was. A wooden ceiling with knots in the grain. The sound of a Long Island night through the near-but-not-drafty window. The smell of pine and salt and the specific smell of a space occupied by adolescents with divine blood, which was like the smell of other camps but with something underneath it that was older and stranger.
It was real. He was real here. This was not a story he knew; it was a place he was in, and the difference between those two things, which he had understood intellectually for years, arrived in him that night as a physical fact.
He thought: tomorrow I meet Annabeth Chase. She is nine years old and she will be the sharpest mind in any room she enters for the rest of her life and I should not, under any circumstances, underestimate her or condescend to her or treat her as a character I already know.
He thought: I need to practice treating everyone I meet here as a person rather than a person I have advance information about.
He thought: this is going to require more active effort than almost anything else I do here.
He closed his eyes. The camp breathed around him. For the first time in a very long time, he slept somewhere that was not his parents' house, and the unfamiliarity of it was not uncomfortable but something else — the particular sensation of a new room accepting you into it.
