I know everyone will have a different take on this, but it is true that many readers want different things from the get-go. Some want to learn who the characters are and to have a reason to pull for them before they are subjected to life’s trials. Other readers want to jump into the action and learn the background in steps when it is absolutely necessary.
Giving technical background information is helpful to some readers and loses others. Not adding the enticing details robs some readers of their enjoyment and feeling that they can step into another world. It is the perfect balance which wins the most readers.
I’ve heard many writers say that if you only read the entire book you will see why I did certain things as I did. If you have a loyal reader base—this will happen. If not, the reader will scan kindle for another date to spend time with.
So, with this as an introduction—what are your expectation as far as pace is concerned in a great book?
