History remembers. The dead do not forget.
The windmill is whispering—and it's not the wind.
When the Ford Motor Company contacts Ghost Healers, Inc. with an urgent request, Ellen, Sue, and Tanya travel to Greenfield Village in Dearborn, Michigan, where tourists have begun hearing disembodied voices near the historic Farris Windmill. What starts as a simple haunting quickly spirals into something far more dangerous.
A shadow in a black hat.
A voice from a phonograph.
A plea for help from beyond the grave.
As the trio digs into the village's history, they uncover a chilling connection to Thomas Edison himself—one that involves guilt, ambition, and a secret experiment that should never have been attempted. And someone in the world of the living is determined to keep the truth buried.
When a portal between realms threatens to tear open, Ellen and her friends must decide how far they're willing to go to close it—even if it means confronting a legacy that shaped the modern world.
Because this time, they're not just untethering a ghost.
They're standing at the center of something much bigger.
And the windmill is still whispering.
