This is a story about trees and fungi connected through a "wood wide web" told by one tiny fungal spore.

A little fungus meets a baby cacao tree and they learn to feed each other. They cooperate with a forest of plants and a metropolis of microbes in the soil. But when drought strikes can they work together to survive?
