A Caldecott Honor Book Four starred reviews! “Both gloriously expansive and goofy—in short, everything young readers could ask for.” —Kirkus Reviews (starred review) A hilarious and thought-provoking picture book about two little cave rock formations who witness the entire history of the world, perfect for fans of Oliver Jeffers, Jon Klassen, and Mac Barnett. DRIP. DRIP. DRIP. Time flies for two charming little cave nubs, Stalactite and Stalagmite. Over millions of years, creatures and things pass in and out of their cave, everything from a trilobite, an ichthyostega, and a triceratops, to a ground sloth and a bat. When you are an ageless rock formation, it’s nice to have a friend who’s always there. But what will happen when the two nubs grow enough to finally touch?
