‘Suddenly, it was everywhere’: why some books become blockbusters overnight

Sun, 14 Dec 2025

Whether it’s through TikTok buzz, celebrity endorsements or good old-fashioned word of mouth, some titles enjoy a second, more powerful, life. But what unites them – and is there a formula for this type of success?

There is a particular kind of literary deja vu that strikes sometimes. Seemingly out of nowhere, the same book starts appearing across multiple social media feeds. On the bus, you’ll spot two copies of the same title in one day. A friend says, “Have you read this yet?”, to which you respond, “Someone was just telling me about it the other day.”

These are the sleeper hits that seem to materialise without warning. They are not stacked high on the new release tables. They are books that, for one reason or another, have slipped their original timelines and found a second, often more powerful life.
