Angels are everywhere, in more ways than one.
Authors can barely write fast enough to keep up with America's fascination with the ethereal creatures, which some people say is an indication of increased angel activity on Earth.And producers of images of angels - be they ceramic, stained glass or drawings - are working just as furiously to keep up with demand.
"It's amazing," Tim Jones, author of "Celebration of Angels," said during a panel discussion at the 45th annual Christian Booksellers Association convention at the Colorado Convention Center.
"There is a hungering for the divine. People are realizing there is something more" - things science cannot explain, events and human behaviors we cannot always understand, he said.
Phyllis Tickle, religion editor of "Publishers Weekly" magazine, said: "In a culture that is as violence-prone as this one is, it's nice to have something on your side."
And for many, angels - described in the Bible as the doers of God's work on Earth - fill the bill, she said.
Not all of the panelists agreed angels are more active than in the past. After all, how does one go about measuring such a thing?
But the Rev. Charlie Shedd - a believer - said it's because people have invited angels to come.
Said to be manifestations of God, angels must feel God is welcome in order to make themselves present, said Shedd, a Presbyterian minister and author of 35 books, including "Brush of an Angel's Wing."
Tickle said there are at least 32 new titles rolling off the presses. They should be on the shelves by February.
John Adams, representing one of hundreds of companies displaying Christian products at the convention center this week, said his Minnesota-based firm once made decorative stained-glass items in all sorts of shapes and sizes. The firm, Glass House of Minnesota, went strictly angels in the mid-1980s.
"We just found they really supported the company," Adams said.
"I do believe there's a place for all of this," he said. "There are things we cannot explain."
