Fayerdale was named by a wife of one of the owners of the Virginia Ore and Lumbar Company. She used the names of her husband and another owner's middle name F from Frank, Ayer, and Dale. How did she come up with that combination? Fayerdale Drive is an actual road near Fairy Stone State Park. It is gravel, but you won't find a real-life version of Joan's house. That one came from my imagination.
I thought having Joan live on Fayerdale drive would be a cool way to link the past with the future even before the reader realized there was any connection between the two (in the supernatural sense any way). I love weaving the fantasy portion of the story with real life places.
