High Spirits — Dianne K. Salerni

In mid-nineteenth century America, spirits knock and tables tip for Maggie and Kate Fox, two teenage sisters who convince people they can talk to the dead with their mysterious rapping noises. Before long, neighbors are begging Maggie and Katie for the chance to receive messages from dead relatives and older sister Leah realizes that their “prank” has real money-making potential.

Soon, the sisters hit the road to bamboozle newspaper editors, politicians, and the public at large and start a national craze for spirits and ghosts. Their fame grows -- but could their powers actually be real? See the good and the bad that can happen when three sisters land in the limelight and come to their own conclusions about what's true, what's right and what's important.
