The idea was Kaelan's, which should have warned me from the start, since Kaelan's ideas had a long and storied history of ending with one or both of us in trouble.
"A binding rite," he said, sprawled backward on our boulder with his hands laced behind his head, looking at the sky like he could already see the moon that wasn't due to rise full for another two weeks. "My grandmother used to talk about it. Witches and wolves, way back, before the packs and covens decided they didn't like each other much. A friendship rite. You do it under a full moon, and it's supposed to bind you as kin not blood kin, but something almost like it."
"And you know how to do this rite because…?"
"Because my grandmother told me stories when I was little and apparently I remember everything, unlike some people who can't remember not to skip stones badly."
"I have improved," I said, with as much dignity as I could manage, which was not much, because we both knew perfectly well I had not improved.
I was fifteen that autumn, Kaelan sixteen, and we had spent enough years by then treating the clearing as our own private country that the idea of doing something there under the full moon didn't feel reckless so much as inevitable. I didn't ask my mother. I told myself it was because I didn't want to bother her, though the truer answer was that some small, sharp part of me already suspected what she'd say, and I wasn't ready to hear it not about the rite itself, and not about everything I'd been quietly carrying where Kaelan was concerned since the year before, the warmth I still hadn't found the courage to name out loud to anyone, not even Wren.
We met at the boulder two weeks later, on the night the moon hung round and heavy and close, low enough over the ridge that it looked almost near enough to touch. I'd brought what I could gather without my sisters noticing a length of red thread, a sprig of rosemary for remembrance, a small dish for the herbs I'd need to burn. Kaelan brought nothing but himself, which I teased him about mercilessly until he pointed out, reasonably, that the wolf half of the rite didn't require props, just presence.
"That's very convenient for you," I said, kneeling to set out the dish.
"I contain multitudes."
"You contain approximately one joke, which you've now used four times tonight."
The clearing was different by moonlight. I'd seen it in every kind of daylight there was, but the moon washed all of that color out and replaced it with something quieter, silver and deep, the shadows between the birches gone soft and blue instead of black. The stream caught the light and threw it back in broken pieces, and somewhere above us an owl called once and went silent, as if it too understood that something was about to happen that deserved a hush.
I lit the rosemary in the dish, and the smoke curled up between us, sweet and sharp at once, and I felt the particular hum of the clearing's edges wake up around us the way my mother's cottage sometimes woke at dusk not loud, not dramatic, just a low awareness settling over the air like a held breath.
"Now what?" I asked.
"Now we tie the thread. One end each. My grandmother said you're supposed to speak something true while you do it. Something you haven't said out loud before."
"That seems like an oddly specific requirement for a friendship rite."
"Magic's specific like that." He held out his hand, and I looped the red thread twice around his wrist before tying it, my fingers clumsier than I wanted them to be, not because the knot was difficult but because his pulse was right there under my fingertips, quick and warm, and it was strange to be so aware of another person's heartbeat when I'd already spent a year being far too aware of everything else about him.
"Your turn," I said, holding out my own wrist.
He tied the other end around mine with more care than I expected, tugging it gently to test the knot, his knuckles brushing the inside of my wrist in a way that sent a small, familiar current up my arm familiar, because it wasn't the first time this year my body had reacted to him like this, though it was the first time the reaction had felt quite this loud. Neither of us said anything about it.
"So. Something true," I said, mostly to have something to say. "You go first, since it was your idea."
Kaelan was quiet for a moment, looking not at me but at the thread joining our wrists, turning his hand slightly so the moonlight caught the red of it. "I used to be scared you'd get tired of me," he said finally. "When we were kids. I kept thinking, she's a witch, I'm a wolf, one day she's going to realize how strange this is and stop coming to the clearing." He glanced up, and the moonlight did something to his eyes that made them look less gold than silver, less like a wolf's and more like something I didn't have a word for. "You never did, though. Realize it, I mean. Or if you did, you didn't care."
I hadn't expected that. I'd expected a joke, or something easy, something in the register we usually spoke in. This was quieter, and truer, and it settled somewhere under my ribs and stayed there.
"I never thought it was strange," I said, and found that once I started, the rest came easier than I expected. "I think you're the only person who's never made me feel like I had to be anything other than exactly what I am. My sisters love me, but they know exactly which parts of me to press when they want something. You've never once done that. You just…" I stopped, searching for the true thing underneath the thing I was about to say, aware that the truest thing I could say was bigger than I was ready to hand him yet. "You just let me be whoever I am on a given day. That's rarer than I think you know."
The owl called again, closer this time, and the smoke from the rosemary curled between us like it was listening too. Neither of us moved. The thread sat warm around both our wrists, and the moon hung there over the ridge, patient and enormous, and for a long moment the whole clearing seemed to hold very still, as if it, too, understood that something had shifted, some quiet threshold crossed that neither of us had a name ready for.
"I don't know what the rite's supposed to feel like when it works," Kaelan said eventually, voice lower than before.
"Maybe it doesn't feel like anything. Maybe it's just the thread and the words and we go home and nothing's different."
"Doesn't feel like nothing," he said. Just that. Four words, quiet in the dark, and I didn't ask him to explain them, because I understood exactly what he meant, and understanding it scared me a little, given everything he'd told me only a season before about fated bonds and the wolves who got left behind waiting for one.
We sat like that for a long while after, shoulders pressed together on the cold stone of the boulder, watching the moon climb, not speaking much, the red thread linking our wrists loose enough now that neither of us bothered to untie it. I don't know how long we stayed. Long enough that the rosemary burned down to ash in the dish. Long enough that the owl called a third time and finally flew, a dark shape crossing the moon's face and gone.
When I finally walked home, the thread still around my wrist, I found my mother sitting up by the hearth, waiting for me the way she sometimes did on nights she suspected I'd been somewhere she hadn't sanctioned. She looked at the thread. She didn't ask about it, not directly, though her eyes lingered on it a moment longer than they needed to.
"Good rite?" she asked instead, mild as anything, stirring something in the pot over the fire.
I startled. "How did you…"
"Rosemary smoke clings to hair," she said, and there was something in her voice I couldn't quite read, not disapproval, exactly, but a kind of careful watching, the way you watch a pot that hasn't boiled yet but might. "Go to bed, Seraphina. You'll want your rest."
I went, the thread still tied loosely around my wrist, my heart doing something loud and unfamiliar in my chest, some quiet, private thing I didn't try to name that night, because it felt, for once, like a thing better left unnamed a little while longer.
