Amazon.com Product Description (ISBN 037586900X, Hardcover)

Halloween is nearing, the one day of the year when the ghostly plane is close enough to the human plane to allow mischief and mayhem. But the ghosts who have their eye on Zack aren't thinking mischief, they are thinking murder.

In this fourth volume of Chris Grabenstein's popular Haunted Mysteries series, Zack must once again do battle with malevolent spirits. And with his usual pluck, and the assistance of three dotty aunts, he must save his town from a 200-year-old threat.

Once again Chris Grabenstein proves his mastery of the frightening and funny tale. Young readers, especially reluctant ones, have found an inspiration to read in Grabenstein's quirky characters and deadly situations.
