QUESTION: Why don't authors keep writing the same kind of book? Some of my favorite romance authors have switched to different genres, and I HATE it.
There isn't a simple answer. Here are a few.
* Failing markets. The writer's genre starts losing readers so publishers want fewer books, and fewer books are sold. An example is historical romances. Its established authors branched out into contemporaries, paranormals, and suspense novels to continue making a profit at their writing.
* Respect. Romance authors, in particular, get no respect from their non-romance peers, and this gets really old. Non-romances also have more professional cache.
* Authorial control. Romance editors exert more control over the final product than in any other genre so the final product is often more of a collaborative effort. At a certain point in a writer's career, this can get really old, particularly when some kid in their first editorial job decides she knows better than an established writer.
* Boredom. An author spends months writing a book that takes you an evening to read, and she then starts another book. If every book is exactly like the last as some readers want, this process can become boring. The creative juices dry up. If the author doesn't change gears, the readers will be the next to be bored.
* Innovations. Genre, as a whole, doesn't stay the same. Romances have changed dramatically over the last twenty years, and woe unto the writer who doesn't change with it.
* Bandwagon Syndrome. Some authors see a trend become popular, and they absolutely must write to this trend.
* Changes in an author's life. Writing is an emotional process, and sometimes, things happening in an author's life make them change the direction of their writing. I have had friends going through an ugly divorce who could no longer write about everlasting love when their true love proved to be a cruel, manipulative jerk. One writer lost her young son to a sudden illness. When she started writing again, she turned to novels that expressed her faith in God.
As much as writers want to please their readers, sometimes, they simply must change direction with their writing.
