Enter the Earth is the first book in the Gaia Girls Book Series. Four girls, each from a different place in the world discover they can talk to Gaia-the living organism of the Earth. Gaia gives them power with earth, air, fire or water and they have to help right environmental wrongs. In Enter the Earth, a fourth-grade girl from upstate, NY has to learn to use her "gaia powers" to save her family's organic farm from an incoming factory farming operation.
