Gaia Girls: Enter the Earth - Lee Welles

Elizabeth Angier was happy to be at the end of the school year. She thought her summer on the family farm would be full of work and play with her best friend, Rachel, and her other best friend, her dog, Maizey. However, Elizabeth didn't anticipate the Harmony Farms Corporation moving to her town. Her world starts to crumble as her best friend moves away and her parents whisper of farmers selling their land and the effects this factory farm operation could have on them. When she thinks things can't get much worse, she meets the most unusual creature, Gaia, the living entity of the Earth. Strange things begin to happen to her, around her, and through her! Elizabeth discovers that with these new powers comes responsibility. A dire mistake makes Elizabeth wonder if meeting Gaia has been a blessing or a curse. Will Elizabeth have the strength to fight a large corporation? Or will her upstate New York home be spoiled by profit driven pork production that fouls the air, land, and water?
