An interesting related issue is: how soon in a novel does the author have to hit the reader over the head with excitement? Should it be the first line? The first paragraph? Or do we have at least until the end of the first chapter? Of course, this does vary by genre. (Literary novels never have to have anything exciting happen. :) Ha. I kid the literary authors.) A few years ago, I would have said we had until the end of the first chapter. But now, with the increased pressure to sell books I'm thinking a bang! pow! novel first line is not a bad idea.
What do you think?
