Dark matters

"In an isolated house at the edge of a cornfield, in the mountains of Virginia, something almost beyond belief is happening to the Cleary family. When Bridget Cleary goes missing, in the dead of night, her husband, Michael, and son, Jeremy, scramble to help Sheriff Richard Egan find her. Then, as suddenly as she vanished, Bridget reappears, talking about strange visitations and otherworldly beings."--P. 4 of cover.
