Minerva Clark's yoga-instructor mom has returned-with a new husband in tow. As if that isn't a big enough shock, there's a surprise of the supernatural sort in store for the self-made teen sleuth. It seems the owners of a haunted grocery store are missing their ghost, and they need Minerva's help in finding it. But before she can come up with the ghost, Minerva will need to find the arsonist who burned the grocery store to the ground. Danger, laughs, and a touch of freezer burn await readers in this newest adventure from the big-haired case-cracker.
