Steve Light's Swap! is a charming visual puzzle disguised as a maritime story. When a ship captain is stuck with a broken-down boat, his young mate starts with a single loose button and barters his way up—trading the button for teacups, teacups for rope, and rope for oars—until they have everything needed to fix the ship and set sail.
It introduces the basic mechanics of trade and value to early readers without feeling preachy. The pen-and-ink illustrations are packed with tiny details that reward kids who like to linger on a page.
