Book 3: Sand Sack

What’s cooler than a geodesic tent? Igloos! (They have the same basic overall shape). Also cool: learning that the straight lines of their family tent’s triangles and an igloo’s square-ish blocks of snow are arranged to make surfaces that are rounded. What’s hot? Climbing sand dunes in summer. Mallory’s seven-year-old twin sister, Melody, enjoys the heat. Mallory? Not so much.

Mallory and his Dad head back down the dune while his Mom and sister continue their upward trek. In the shade of a small bush, Mallory discovers more than cooler sand as he settles into a little trench that his dog Rufus helped to dig. When Mallory and his father visit the local Indiana Dunes police station to turn in their find, they learn why some dunes are called “living.”
