From my upcoming novel, Small Town Witch, Chapter 5, “The Faeriekin Party”:

I pointed to a pond filled with water lilies and floating candles. “That’s the dance floor.”

Heather stared in confusion. “I don’t see anything.”

“It floats in mid-air. It’s invisible so you can see the pond.” I pointed to a space flanked by two white crane statues. “That shows you where the way up is. There are more ballrooms inside.”
