"Fourth Wing" by Rebecca Yarros tops TikTok's first Europe-wide #BookTok bestseller list 2026. For the German book market, however, the ranking is only part of the story: according to the Media Control analysis published by TikTok Media Control analysis, Caroline Wahl's "22 Bahnen" ranks first in Germany. An accompanying survey also shows that creator recommendations reach as far as bookstores and literary events. The key is not to confuse sales data, community statements and proven impact.
The European list – and the clearly different German leader
At European level, according to TikTok and Media Control, the titles following "Fourth Wing" are "Binding 13" (Chloe Walsh), "Heated Rivalry" (Rachel Reid), "The Mistake" (Elle Kennedy) and "Saving 6" (Chloe Walsh). Chloe Walsh is identified as Europe's especially successful BookTok author. The list aggregates several countries; it is not a ranking of the most-viewed individual TikTok videos.
In Germany, by contrast, "22 Bahnen" by Caroline Wahl comes out on top; "Windstärke 17" also reaches a top-five place. Behind them, the German annual ranking includes "Die LET THEM Theorie", "Die Psychiaterin" and "Alchemised", among others. This matters for publishers: European trend dynamics do not mean the same titles are bought everywhere. Local language, backlist, bookstore presence and target audiences still play a role.
The BookTok bestseller lists started 2023 in Germany, were 2024 extended to Austria and Switzerland, and now also cover the UK, Italy and Spain. The annual analysis uses Media Control data; for the German ranking TikTok names September 2025 to August 2026 as the reference period.
From recommendation to shelf: what the numbers say
TikTok refers to an earlier analysis by NielsenIQ BookData and Media Control: 2025 books recommended in the context of #BookTok were sold across the European markets examined, over 50 million units; associated revenue exceeded 800 million euros. This is an attribution of recommended titles to book sales, not proof that every purchase would have failed to happen without TikTok.
The new Qualtrics survey commissioned by TikTok, 22 to 29 September 2026, offers a different perspective. Among the surveyed TikTok users in Germany from the relevant BookTok community, 74 percent said they let creator recommendations inform purchase decisions. 50 percent said TikTok had inspired them to buy a book or audiobook; 51 percent said they had already bought from independent bookstores on site. For 63 percent it was about new genres or diverse voices, and 46 percent reported visiting a book event.
These answers reflect self-reported information, not causal additional sales. The German sample comprised 500 TikTok users aged 16 and older; it cannot be equated with a representative survey of all German book buyers. The sales data and the survey use different collection methods and time periods.
Three consequences for publishers, bookstores and creators
1. Backlist, not just new releases: A title can resurface in the feed as a rediscovered recommendation long after its first sale. For publishers, it therefore pays to monitor author, genre, existing editions and demand – not just publication weeks.
2. The trade as a second touchpoint: Bookstores can pick up social trends with shelf displays, events and local advice. Whether this lifts sales is better tested with comparable branches, sales periods and reorders than with video views alone. We explore the basic principle of how social demand meets physical shelves using the example of Mellow Sleep at Target.
3. Evaluate creators and commerce separately: Organic reading enthusiasm, paid partnerships and publisher campaigns are different things. For creator briefings, what counts is genuine reading experience, transparently labelled advertising and traceable links. How difficult impact measurement across platforms remains is explained in our article on creator marketing measurement; the differences between attention and confirmed sales are also covered by the TikTok Shop analysis of creator patterns.
Why this ranking is more than a marketing award
For the first time, European bestsellers on TikTok sit alongside concrete German book market results. Together, these make BookTok a useful field of observation for marketing teams – but it should not be sold as a general guarantee of book sales. More interesting than a single viral video are recurring recommendations, reliable bookstore data, and the question of which reader groups a title reaches anew.
