Readers of romance buy at a rate no other category matches, frequently working through several books a week. The pattern is produced by how the genre is built rather than by any difference in the readers themselves.
A guaranteed ending removes the risk
The genre's defining convention is that the central relationship resolves satisfyingly. A reader knows the emotional outcome before opening the book.
That certainty makes each purchase a low-risk decision, because the worst realistic outcome is a book that is merely dull rather than one that betrays the reader.
Low-risk purchases are made quickly and often, which is the foundation of the volume the category sustains.
Readers who have been disappointed by a book still return to the genre, because the disappointment was with one author rather than with the promise itself.
The books are written to be read fast
Romance is generally shorter than other adult fiction, with scenes structured around emotional beats rather than accumulating plot.
A book that can be finished in an evening produces the moment of wanting another one far more frequently than a long novel does.
Publishers and independent authors both write to that rhythm, since the reading pace sets the buying pace directly.
Tropes let readers find what they want precisely
The genre has developed an unusually specific vocabulary for its situations, and readers use those terms to search for exactly the experience they are in the mood for.
This shortens the distance between finishing one book and choosing the next, because the reader is not browsing broadly but requesting a known thing.
Retailers and reader communities have adopted the vocabulary, which makes discovery faster here than in categories that describe themselves more vaguely.
Series are built to be continued
Connected books following different couples in the same setting let a reader stay in a world without waiting for one storyline to resolve.
Each book both concludes and advertises the next, and a reader arriving at any point in the sequence has a backlist waiting.
Secondary characters are introduced with their own future books in mind, so the structure creates demand for titles that have not been written yet.
The economics follow the habit
Because readers consume so much, the category supports frequent publication, lower prices and a large independent sector serving demand faster than traditional schedules allow.
Every structural feature of romance publishing exists because the audience finishes books quickly and immediately wants another.
