Spooked! — L.L. Bartlett

The trick-or-treaters have gone home and now it's time for the adults to celebrate All Hallows Eve. When Maggie suggests they consult an Ouija board, Jeff Resnick thinks it'll be anything but fun. And when they conjure up a ghost from Jeff's past, the game turns dangerous for the most vulnerable person in his life. (This short story directly follows Dark Waters.)
