From Texas, from California, from all corners of Missouri, they came, 1,200 strong — with a few stragglers in search of long-since sold-out tickets to hear Stephen King on Sunday night.

And when King and his co-author, son Owen King, took the stage at Lindenwood University to boisterous applause, there was an audible sigh of contentment.

The Kings first read an excerpt from their new novel, “Sleeping Beauties” — and said the Griner Brothers in the novel got their name from a reference in “Deliverance.”

The father-son duo then asked each other some questions, and talked about how fans frequently pitch story ideas to King the senior.

“Why don’t you write about Trump? That would be a real horror story,” Stephen King said they ask him.

Both writers said story ideas just come from some inner well — and the genesis for “Sleeping Beauties” was Owen.

“What if one day all the women in the world didn’t wake up?” he asked, adding that he was the father of a very young child and “very sleep deprived.”
