How a Gram Crosses a Continent
Four Journeys into How a Butterfly Survives the CrossingBy Rowan Cassidy
Length47m
About this audiobook
How does something lighter than a raindrop cross a continent? In four vivid, audio-crafted journeys, this second volume follows the monarch's astonishing crossing — the half-gram glider that rides the sun's rising air instead of fighting it, the caterpillar that performs surgery on a poison plant and steals its venom for armor, the slow autumn feeding that fuels a body for a winter it has never felt, and the moment a butterfly arrives, for the first time, at a mountain it has somehow always been coming home to. Stories of flight, defense, survival, and a homecoming to a place never seen.
