The Vortex of Éire Series by Grace Bridges

How far would you chase hope? What if you could change the world? The green has gone from Mariah's Ireland. Every garden and field that was once lush with crops is now lifeless muck. And yet Mariah holds one seed...the seed of hope. Together with Liam, her staunchest supporter, Naomi the biologist, Deborah, whose son sold out to the Senate, and Peter the farm boy, she sets out to make Ireland green again. That is Mariah's hope. It is Mariah's dream. Mariah's dream will change everything.
