The sixth-year girls’ dormitory in Ravenclaw Tower had been transformed over the summer by house-elves who seemed to understand, instinctively, that its three remaining occupants had outgrown the standard arrangements. Where once there had been five identical four-poster beds arranged in a neat semicircle, now there were three larger beds positioned to create a kind of conversation triangle, with a shared sitting area in the center featuring mismatched armchairs that somehow complemented each other perfectly—one deep blue velvet, one silver-grey linen, one patchwork of fabric scraps that shifted color depending on the light.

Hermione suspected Flitwick’s influence. The Head of House had always shown a particular fondness for their unlikely trio.

Luna Lovegood was currently upside-down on her bed, her bare feet propped against the headboard and her silvery-blonde hair cascading off the edge like a waterfall, pooling on the stone floor. She was gesticulating wildly as she spoke, her radish earrings swinging in chaotic arcs. She was telling them about attending summer school at Cambridge.

“—and the libraries, Hermione, you would simply die. They have a copy of the Venerable Bede’s original manuscript of the Ecclesiastical History and the librarians just let me touch it. With gloves, obviously, but still. I touched something that a saint touched. Or possibly a very scholarly demon pretending to be a saint, which would explain some of his more questionable theological positions, but either way—”

“Luna,” Cho interrupted gently, looking up from the trunk she was unpacking with methodical precision, “you’re going to pass out if you keep talking upside-down like that.”

“Nonsense. The blood rushing to my head improves cognitive function. The ancient Druids knew this. Why do you think they spent so much time hanging from oak trees?”

“I thought that was a mistletoe-harvesting technique,” Hermione offered, settling cross-legged on her own bed with Schroedinger immediately claiming her lap. The ginger cat had been agitated all day—the train ride always unsettled him—but now he was purring with fierce contentment, his eyes half-closed as Hermione scratched behind his ears.

“Mistletoe harvesting, cognitive enhancement, communion with the spirit world—the Druids were very efficient. They multitasked.” Luna finally swung herself upright, her face flushed pink and her eyes bright with that particular intensity that meant she was about to say something either profound or completely mad. With Luna, the distinction was often academic.

“But that’s not the point. The point is that Cambridge is everything I ever dreamed of and more, and I’ve decided that I absolutely must go there after Hogwarts, and I’ve narrowed my future career down to two possibilities.”

She held up two fingers triumphantly.

“Only two?” Cho asked, raising an eyebrow. “Last year you were considering seventeen different paths, including Niffler rehabilitation specialist and professional cloud interpreter.”

“I’ve matured,” Luna said with dignity. “Also, I learned that cloud interpretation doesn’t pay well and Nifflers bite. No, I’ve thought about this very seriously, and I’ve decided that after Cambridge I’m either going to become a teacher—”

“That would be wonderful,” Hermione said warmly. “You’d be brilliant at it. Remember when you explained the theory of magical resonance to those third-years? They finally understood it after you compared it to the way songs get stuck in your head.”

“—or I’m going to seclude myself in a cabin on the shores of Loch Ness and write mystery novels.”

“Those are… very different options,” Cho replied.

“Are they?” Luna seemed genuinely puzzled. She sat up, crossing her legs beneath her and tilting her head at an angle that made her look like a curious bird. “They both involve language. Shaping it, sharing it. Making meaning out of chaos. That’s the only thing I’ve ever really wanted to do.”

She began braiding a strand of her hair, her silver eyes thoughtful.

“Teaching would be lovely. Watching someone suddenly understand something is beautiful. I helped a first-year with her Charms essay last spring and when she finally grasped the theory of intentional magic, she actually gasped. Gasped, like understanding was a physical sensation. Which of course it is. The brain releases dopamine during moments of insight. Muggles have studied this extensively.”

“But teaching means being seen. Being public, and I don’t know if I can handle it. Having students and colleagues and responsibilities and schedules. Having to be Luna Lovegood in a particular way, consistently, day after day.” She wound the braid around her finger, unwound it, wound it again. “Writing mysteries in a cabin, I could be invisible. I could use a pen name. Something very ordinary. Margaret Smith. Dorothy Wells. No one would ever know that the author of the Enchanted Tea Cozy mysteries was a strange witch who talks to lake monsters.”

“You’re not strange,” Cho said automatically.

“I am, though. Delightfully so. But sometimes strange is exhausting to perform. Sometimes I wonder what it would be like to disappear completely, the question is really about how visible I want my life to be. I haven’t decided yet. Cambridge will help me figure it out, I think. Three years of being intensely academic—after that, I’ll know whether I want more of it or whether I want to vanish into the mist with Nessie and my typewriter.”

“Typewriter?” Hermione raised an eyebrow. “A muggle typewriter?”

“Typewriters are deeply romantic. All that mechanical clicking. Very Agatha Christie.” Luna flopped back onto her bed again, satisfied with her explanation. “Besides, I’ve heard that the rhythm of typing helps with prose. Something about the physical repetition syncing with the cadence of sentences. Daddy wrote an article about it once—The Percussive Theory of Literary Composition. It was mostly wrong, but interestingly wrong.”

“Either I spend my life surrounded by young minds, watching understanding dawn in their eyes like little sunrises—or I spend my life in solitude, with only Nessie for company, crafting intricate puzzles for readers to solve.”

“You’ll never know solitude while you know me, darling,” Hermione scolded. “What do you think you’d talk to the Loch Ness Monster about?”

” I think she’s very wise but terribly lonely. All those Muggle tourists with their cameras, looking for her, never actually seeing her. It must be exhausting to be searched for so intently and understood so poorly.” Luna’s voice softened. “I think she’d appreciate someone who just wanted to have tea and discuss narrative structure.”

Cho had finished unpacking and settled into the silver-grey armchair, tucking her feet beneath her. “What kind of mysteries would you write?”

Luna’s face lit up with such pure joy that Hermione felt her own heart lift in response. There was something about Luna’s enthusiasm that was infectious—a reminder that the world still contained wonder, even in dark times.

“Cozy mysteries,” Luna said decisively. “Set in small magical villages where everyone knows everyone and the murders are almost polite. The detective would be an elderly witch who runs a shop selling enchanted tea cozies—that’s the ‘cozy’ part, you see—and she solves crimes by reading the leaves at the bottom of her customers’ cups. But the leaves don’t show her the future. They show her the truth, which is much more useful and much more dangerous.”

“I’d read that,” Hermione said honestly.

“The first book would be called A Stitch in Time Saves Nine Lives,” Luna continued, warming to her subject. “Because someone is murdering cats in the village, only the cats aren’t really dead, they’re being trapped in a temporal pocket by a witch who’s trying to harvest their nine lives for her own immortality scheme. Very dark when you think about it, but there would also be a charming romance subplot involving the witch and the local wandmaker, who’s been secretly in love with her for forty years but never said anything because he’s too shy and also slightly cursed.”

Schroedinger, apparently sensing that cats were being discussed, opened one eye and fixed Luna with a penetrating stare.

“Don’t worry,” Luna told him serenely. “The cats are all rescued in the end. I’m not a monster.”

Cho laughed—a genuine, delighted sound that had become rarer over the past year. Hermione noticed that her friend looked tired, thinner than she’d been in June, with shadows under her eyes that spoke of sleepless nights. Whatever Cho had done over the summer, it hadn’t been restful.

But this moment—this silly, wonderful conversation about mystery novels and lake monsters and teaching careers—seemed to be exactly what she needed. The tension in her shoulders was easing. The careful watchfulness that had become her default expression was softening into something more like the Cho that Hermione remembered from before Cedric’s death, before the war became inescapable.

“What about you?” Luna asked suddenly, rolling onto her stomach and propping her chin on her hands to look at Hermione. “What are you going to do after Hogwarts? Besides revolutionize magical theory and probably accidentally save the world?”

Hermione stroked Schroedinger’s fur, considering. “I used to think I wanted to work for the Ministry. Change things from the inside. House-elf rights, werewolf integration, Muggle-born protections—there’s so much that needs fixing.”

“But?” Cho prompted.

“But the Ministry is…” Hermione paused, searching for the right word. “Compromised. The Dark Lord may not have taken it over completely, but his influence is everywhere. The people who want change either get pushed out or… corrupted. I’ve been reading about it all summer. The Department of Magical Law Enforcement used to be independent, but now half the senior Aurors have ties to families that support him. The Wizengamot hasn’t passed a pro-Muggle-born law in three years. Even the Department for the Regulation and Control of Magical Creatures—which should be pushing for creature rights—is mostly focused on ‘containment’ and ‘monitoring.’ As if werewolves and centaurs and house-elves are problems to be managed rather than people to be liberated.”

“So what will you do instead?” Luna asked.

“I don’t know yet. Maybe teach, like you said. Maybe research—there’s so much we don’t understand about the intersection of magical theory and Muggle physics.”

“Quantum superposition,” Cho said softly. “The observer affecting the observed.”

“Exactly. Except in quantum physics, observation is supposed to be passive—you’re just measuring what’s already there. But what if that’s wrong? What if consciousness isn’t just observing reality, it’s choosing it? What if every time we make a decision, we’re collapsing wave functions, selecting one timeline out of infinite possibilities?”

“That,” Luna said, “is either the most brilliant thing I’ve ever heard or complete nonsense. I can’t decide which, which means it’s probably both simultaneously. Superposition of ideas.”

Hermione laughed. “That’s exactly what I mean. The universe might work like that—holding contradictions together until something forces a resolution. And magic might be the force that does the forcing. Willful, intentional collapse of probability into certainty.”

“Is that what the Department of Mysteries studies?” Cho asked. There was something careful in her voice, something Hermione couldn’t quite identify.

“I think so. But they’re so secretive—no one really knows what the Unspeakables do. Just rumors. The Time Room, the Death Chamber, the Hall of Prophecy…” Hermione shook her head and frowned. “It’s scary.”

She stopped. Something had shifted in the room—a subtle tension, a held breath. Luna was looking at Cho with an expression of unusual sharpness, and Cho was very carefully not looking at either of them, her eyes fixed on her own hands.

“What?” Hermione asked.

“Nothing. Just thinking that the Department of Mysteries might be exactly where you end up someday. You’d fit right in with the Unspeakables. All those secrets and equations.”

The moment passed. Luna began chattering about the specific properties of Loch Ness water (apparently excellent for brewing inks that revealed hidden text), and Cho relaxed back into her chair, and the three of them fell into the comfortable rhythm of old friendship—finishing each other’s sentences, sharing sweets from their trunks, speculating about what the new Defense Against the Dark Arts teacher would be like (the position seemed cursed, with a new professor every year).

But Hermione couldn’t shake the feeling that something important had just happened. Some communication had passed between her friends that she had missed, some significance in Cho’s reaction to the mention of the Department of Mysteries.

She filed it away, as she filed away all the things she didn’t yet understand. Eventually, she would have enough pieces to see the pattern. Eventually, the wave function would collapse, and she would know.

Until then, there was this: her friends, her cat, the familiar stone walls of Ravenclaw Tower, the stars wheeling overhead like a promise of infinite possibility. There was Luna planning her hermit-novelist future with infectious delight. There was Cho’s quiet watchfulness, her fierce loyalty, her secrets kept close to protect them all.

And there was tomorrow, when classes would begin and she would see Draco again for the first time since that last dinner at her parents’ house, when he had kissed her in the garden under the willow tree and whispered something into her hair that she hadn’t quite heard but that had made her heart feel like it was trying to escape her chest.

This year, she thought. This year will change everything.

She didn’t know yet how right she was.
