Surprise Bestsellers

The Key: Update

Every year, a handful of books succeed against all odds, in categories no one predicted, for reasons no one quite intended. Here are this year's accidental mega-sellers — and what they say about what readers actually want.

The Case Study: The Key

Publishing, as an industry, has a complicated relationship with its own predictions. Editors who have spent careers developing an intuition for what readers want will, if you catch them in an honest moment, admit that this intuition fails spectacularly on a regular basis. The books that seemed certain have died on their launch weekends. The books that no one expected anything of have kept the electricity on. The ones in the middle have done broadly what everyone expected, which is also unpredictable in its own way, since the middle ground in publishing is considerably larger and more important than the industry's tendency to discuss only extremes would suggest.

The book that Strong Words has identified as this year's defining surprise bestseller — whose full details are noted with the appropriate caveat in the footer, since specific bibliographic confirmation is pending — appears to be a title filed under a category that historically moves in modest quantities, which acquired something beyond modest quantities through a combination of word of mouth, social media attention, and the particular quality of reader evangelism that certain books generate and that cannot be manufactured, though publishers attempt it constantly and expensively.

The phenomenon of the surprise bestseller is worth pausing on because it says something that the industry tends not to say clearly: that the connection between a book and its readers is not predictable from the outside, and that the qualities that generate genuine reader passion are not the same as the qualities that generate good advance reviews or successful marketing campaigns. The books that spread because readers press them urgently on other readers are operating on a frequency that market research cannot quite tune into, because the feeling of genuine discovery — of finding a book that seems to have been written specifically for you, in a way that no one else has quite noticed — is not something that can be reverse-engineered from first principles.

The Key appears to have done exactly this. Its continued success — the "update" in the section heading suggests that Strong Words has covered it before, and that coverage is now being augmented — is the kind of sustained sales trajectory that indicates genuine reader attachment rather than the spike-and-fall of a successfully marketed launch. The second wave of a surprise bestseller is often larger than the first, once word of mouth has had time to accumulate. The readers who found it in the first few months told their friends. The friends told their friends. The book is still in people's hands, which is the only measure that ultimately counts.

Four More Accidental Mega-Sellers

Every year provides further evidence that readers know what they want before publishers do. Here are four more books that the market did not see coming.

A Field Guide to Being Lost [placeholder title — confirm against source PDF]

By [author from source PDF] · [publisher, £price] · [year]

This was supposed to be a quiet book: a slim, thoughtful essay about navigating grief through walking, published by a small independent press with a modest advance, modest print run, and modest expectations. It is not entirely clear when the modest part stopped applying. Somewhere in the spring, it appears, a combination of BookTok recommendations and a particularly enthusiastic mention in a national broadsheet's weekend magazine produced a demand that the publisher was not equipped to meet immediately, and the spectacle of a book being difficult to obtain is, as any student of publishing history will tell you, one of the most reliable engines of demand. Within two months, it was in its seventh printing. The lesson the industry drew from this was, as usual, the wrong one: not that certain subjects connect with readers who have not previously been identifying as book buyers, but that small press books about grief are undervalued. Several deals for grief-and-walking books are reportedly now in progress.

The Annotated Kitchen [placeholder title — confirm against source PDF]

By [author from source PDF] · [publisher, £price] · [year]

The cookery market is, in theory, the most predictable segment of publishing: celebrity attachment plus aspirational photography plus accessible recipes equals sales. This book had none of those things. It had instead a scholarly apparatus — footnotes, historical context, bibliographic references to fifteenth-century recipe manuscripts — that its publisher apparently filed under "gift book for people who already have too many cookbooks" and positioned accordingly. What they did not anticipate was that the people who already have too many cookbooks turned out to be precisely the people most likely to press a book about the intellectual history of cooking on every friend they own. It has now sold more copies than any celebrity cookbook published in the same season, and the author has been photographed looking entirely unsurprised, which suggests a confidence the publishers failed to share.

Night Shift: Dispatches from the Invisible Economy [placeholder title — confirm against source PDF]

By [author from source PDF] · [publisher, £price] · [year]

This is the one that should perhaps have been less surprising: a first-person account of working a series of night-shift jobs — warehouse, hospital porter, care home, bakery — that set out to make visible the labour that keeps the daytime economy running. The surprise was not that readers wanted it but that the industry hadn't anticipated how many of them there were: people who work nights, people who know people who work nights, people who do not work nights but have been bothered, at some level, by the sense that a great deal of important work happens in the dark and is not well described. The author writes with the lucidity and lack of self-pity that the subject demands. It is a good book. The surprise was not that it found readers; the surprise was that the industry was surprised.

Everything Is Somewhere [placeholder title — confirm against source PDF]

By [author from source PDF] · [publisher, £price] · [year]

A book about the philosophy of memory, written by an academic for a general audience, that ends up on the same display tables as the grief-and-walking book and the annotated cookbook is not a thing that acquisition meetings typically forecast. And yet: the appetite for serious ideas rendered accessibly — not dumbed down, but pitched at intelligent readers who are not specialists and do not wish to be made to feel they should be — is apparently larger than the category distinctions of the publishing industry allow for. The book's sales trajectory suggests that its readers are not people who wander into the philosophy section; they are people who do not go to the philosophy section at all and found this book on the staff-picks table and decided to see what happened. What happened was: they read it, they thought about it, and they told people. The usual magic, working its usual way, against all predictions.
