Sam & Dave Dig a Hole by Mac Barnett, Illustrated by Jon Klassen

Are we there yet? Is this as good as it gets? How long should we keep looking? To explore these age-old questions, Sam and Dave (along with their surprisingly insightful dog) resolve to keep digging until they find “something spectacular.” Join them in this hilarious cross-sectional view as they tunnel through the earth. You’ll never guess what happens!-Michelle
