His birthday fell on Tuesday the first of March, which was a weekday, which was not the worst thing — a weekday had its own structure, and the structure gave the occasion something to be distinct from.
He came down to the common room at half six and found Hermione already there, which was the same as third year and was, by now, simply how this worked.
'The kettle,' she said. She was at the table with her Runes text and the quality of someone who had been there long enough to have made tea in the interim. There was a cup already poured. She had used the good tin, the one from the second shelf of his dormitory bookcase, which required some thought about exactly when she had been in the dormitory at half past five in the morning, which he decided not to pursue.
He sat. He drank the tea.
'How long?' he said.
'Six,' she said. 'Ish.'
'It's half six.'
'I was reading,' she said.
She put a package on the table. Plain brown paper, the practical double knot she used for everything. He unwrapped it and found a book — small, the specific density of old paper, the binding repaired at some point in a previous century with thread that had been chosen for strength rather than appearance. He opened it carefully.
The title page was in Latin. He read it once and understood what he was holding.
'Where did you find this,' he said.
'An auction house in Edinburgh,' she said. 'In December. A private estate sale — a wizarding family dispersing a library. I wrote to the auctioneer in October and asked to be notified if anything relevant came up.' She had the quality she had when something had arrived at the correct conclusion through the correct process and she was allowing herself to be satisfied by the correctness. 'It's the only copy I could find outside of the Bodleian's restricted collection. The auctioneer confirmed the provenance.'
He held the book with the care it required.
'Thank you,' he said.
'You're sixteen,' she said. 'It seemed like a sixteen book.'
Harry arrived at seven with the expression of someone who had remembered what day it was on waking. He put a package on the table — flat, rectangular, lighter than expected. The wrapping was precise in the specific way of someone who had decided that wrapping a thing correctly was part of giving it.
Inside was a book. Not old, not rare in the usual sense — a field manual, the kind produced in small numbers for specific professional use, this one from the Auror training programme and not commercially available. Handwritten annotations in a previous reader's hand throughout, the marginalia of someone who had used the manual in actual field conditions and had been honest about what worked and what did not.
'Sirius had it from the original,' Harry said. 'From his training. He said to pass it on when the time was right.' He looked at Ron with the quality he had for the things that were not performances. 'He thinks the time is right.'
Ron looked at the annotations. He recognised the handwriting from letters — not Sirius's hand but close, the family resemblance in letterforms that ran through the Black family. Regulus, possibly. Or someone from that generation, someone who had gone through the training and had carried the manual into the war and had been honest with the pages about what the training had not prepared them for.
'Thank you,' he said.
Neville came down with his Herbology notes and a flat package wrapped in the brown paper he always used, slightly inexpertly, which was consistent and which Ron found, each year, simply Neville. He had the settled quality that had been in him since January — the upright ease, the absence of the old hesitation.
The book was thin, old, the cover plain cloth in a green that had faded to something between sage and grey. Neville put it on the table with the specific care of someone who had handled it multiple times in the past week and knew exactly how much care it required.
'Gran had it,' he said. 'In the family library. She said it had been there since my great-uncle's time and nobody had looked at it in forty years and she thought you might.' He looked at Ron steadily. 'It's on magical plants used in ritual preparation. Specific to the tradition you've been working in.' A pause. 'I read the relevant chapters. It's the right period, the right theoretical framework. There's a chapter on living anchors that I think you'll find useful.'
Ron looked at him.
'You read it,' Ron said.
'I wanted to know if it was worth giving,' Neville said. 'It is.'
He was right. Ron could tell from the chapter headings alone. He filed it under the specific category of things to read before March was out and looked at Neville with the particular regard he had for people who gave things they had already vetted.
'Thank you,' he said.
Luna arrived at breakfast, which was the point she arrived. She placed a package on the table beside his porridge with the unhurried quality of someone who had timed this without appearing to time anything.
The book she had found was the strangest of the four, which was consistent. Slim, the cover handwritten rather than printed, the spine repaired with something that was not quite standard bookbinding material and had an organic quality that he chose not to investigate closely. The contents were in a script he recognised as early Futhark with significant regional variation — not the standard teaching version, the older one, the kind that predated the systematisation. He read the first page and found the material was on perceptual theory, the magical mechanisms of expanded awareness, written from a tradition he had not encountered in any of the Black library's holdings.
'Where did this come from,' he said.
'My father's collection,' Luna said. 'He has a room he calls the difficult room. Most of what is in it is difficult for the ordinary reasons. This one is difficult for the other reason.' She looked at him with the specific quality she had for observations that were accurate without being explained. 'You are one of the few people who would find it useful rather than difficult.'
He held the book carefully. The material on perception and expanded awareness was, he noted, directly relevant to the supplementary ritual he was designing for her in April. He was not going to say this.
'Thank you,' he said.
'Happy birthday,' she said, with the certainty she used for statements that required nothing back.
His mother's card arrived at breakfast by owl — the good stationery, the handwriting that had been the same since he could first remember receiving letters. He read it once and put it in his inside pocket. His father's was a separate card again, which had been the case since fourth year — his father had started writing his own card at some point and had not stopped, and the fact of the separate card was itself a kind of communication that did not require the words inside it to be large.
This year the words inside were: Sixteen is a significant number in magical theory. I looked it up. I think you already knew.
He did already know. He had known since third year, when he had been reading through the Black library's foundational theory texts and had found the annotations on magical age thresholds — the specific significance of sixteen as the point at which a practitioner's core finished its primary development, the reason the serious ritual work traditionally did not begin until this age, the reason several of the Black library's more demanding texts had annotations in the margin at the relevant passages that read: not before sixteen.
He had spent four years working up to this. He was sixteen today. The year ahead was the year the work would be fully operational.
He thought about his father finding the footnote in a library text and writing it on the inside of a birthday card and the specific quality of that — a man who loved him enough to look things up.
He put the card in his inside pocket with his mother's.
In the evening the twins appeared, because the twins always appeared, with a tin that contained the orange sponge birthday cake and the specific buttercream that his mother made and that was slightly too sweet in the way of things that had been the same for sixteen years and were not going to change.
'Happy birthday,' Fred said. He put the tin on the common room table with the quality he had for the moments that were not performances. 'Sixteen.'
'The year things get serious,' George said.
'They've been serious,' Ron said.
'More serious, then,' George said. 'Relatively.'
Ron looked at his brothers — at Fred with his chalkboard-paint room and the shop now running, at George with his specific and irreplaceable way of seeing — and thought about the Burrow before the Wulfhall, about the shed and the ghoul and the garden gnomes, about the specific dense warmth of a family that had been large and loud and entirely itself regardless of the circumstances around it.
'Cut the cake,' he said.
They cut the cake.
The books were on the table around the tin — four of them, in their different sizes and conditions and origins, the specific collection of people who had known what he was and what he needed and had gone and found it. He looked at them for a moment in the firelight and thought about sixteen and what it meant, in the specific technical sense his father had found in a footnote, and in the other sense, the one that could not be found in any text.
He had arrived at it correctly.
That was sufficient.
