All roller coasters are the same, right? Ummm, no.
But they all go up and down, right? Well, yes.
So then they are all the same. No.
That is like saying all historical books are the same. All romance books are the same and so on. (Of course I'm being simplistic.) Yes, all books have similarities, but to keep readers and riders coming, something must be new each time.
David Maass says, "Moral absolutes to not play well in fiction. Fiction is about people, and people are fallible. Also, these manuscripts tend to preach what most of us already believe. Why listen to that? Remember: Even when the message is familiar, the medium needs to be new." Writer's Digest, May/June 2012
So consider the simple roller coaster where people line up to ride them over and over for the thrill and step out of the ordinary ride of life. (These are only 3 out of the 6-7 at Busch Gardens.)
Whatever genre you write, may the twists and turns bring oohs and aahs from your readers and maybe just a scream of delight or fear.
"But I do not consider my life of any account as dear to myself, in order that I may finish my course, and the ministry which I received from the Lord Jesus, to testify solemnly of the gospel of the grace of God. " Acts 20:24
Paul who wrote many of the books of the New Testament, was ambushed by the Spirit of the Lord to turn him from a Anti-Christian-Terrorist (Acts 8:1-9:19) to a Beloved-Christian-Writer. Scripture has many twists with fallible leaders.
Our moral absolutes in life are necessary. In books and roller coasters, not so much.
