Seven-year-old Mallory learns that taking a nine-pound rock from a public park is a lot different from collecting a few pebbles or stones. His twin sister, Melody, doesn’t think it’s such a big deal, but apparently everyone else does. Mallory and his Dad travel back to the Indiana Dunes both to follow up with the local police sergeant on the lost item that Mallory found and also to fulfill Mallory’s hour of public service to settle his debt for removing the rock from the park.
Checking out a bat cave isn’t such a good idea if your dog is along. Humans may not hear the bats squealing, but dogs sure do. Rufus takes off in the opposite direction. Mallory is off to the rescue, except that Mallory himself needs rescuing as he tumbles into a sinkhole.
The Palisades trail gets steeper and steeper. Suddenly, there it is. The great Mississippi River. “How wide is the river?” Melody wants to know, reluctant to leave the magnificent view. She and her brother get a lesson on estimating distances, based on comparing it with things you already know, such as car lengths and soccer fields.
