From the time she first emerged from an egg, the “teeny-tiny creepy-crawly bug” was alone in the world, but she had these words in her head: “Gotta go! Gotta go! Gotta go to Mexico!” Even young readers will observe that this “bug” is a caterpillar and that her journey to Mexico takes her through the various stages of metamorphosis that all monarch butterflies must undergo. Sam Swope’s minimalist art initially uses subdued colors, so the emergence of the orange monarch from her chrysalis is truly glorious. Sue Riddle’s cogent text uses a rhymed refrain that will hold the attention of young listeners. (Ages 3-6)
