In the fourth installment of the Witch of Mintwood series, Lemmi and her friends are visited by ghosts asking for help. This is the first time such a visit has occurred, and Lemmi’s curiosity, not to mention Charlie's, is piqued. Even as they begin to unravel the Missing Hiker Mystery, not all is as it seems. To add to the excitement, there's a town mayoral election, a visit from Lemmi's aunt, and Lemmi’s feelings about Jasper Wolf to contend with.
