Never start a book with a lie.
An editor told me this years ago. What she meant was don't trick the reader into thinking your book is one thing when it's really another. Don't promise a roller-coaster ride when you're really taking them on a sedate merry-go-round.
I've always thought that was great advice.
But I've noticed a lot of lying going on in bookland.
A lot of recently released books start with intense action and violent murder. After that first-chapter hook, the book settles into a slow police procedural, a court-room drama, literary fiction, even a cozy. I suspect many of these opening chapters are added later at the request of an editor.
Has anybody else noticed this trend? What do you think of it? Does it drive you crazy, or do you simply see it as evolution? As publishers doing what they see as necessary to sell books?
