From the "New York Times" bestselling author of "Escape From Mr. Lemoncello's Library" and coauthor of "I Funny" and "Treasure Hunters," comes a series of spine-tingling mysteries to keep you up long after the lights go out. Halloween is near, 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 the fourth volume of Chris Grabenstein's popular Haunted Mysteries series, Zack must yet again do battle with malevolent spirits. And with perseverance and 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 been inspired to read by Grabenstein's quirky characters and deadly situations."
