Fermentation

The fourth entry in the Battle Mage Farmer series follows John as he balances the practical work of running his valley farm, now swelling with refugees fleeing war and famine beyond its borders, against a deepening magical mystery: a decoded doorway spell that may open passage to other worlds, including, perhaps, Earth. While researchers race to calculate a safe destination for the doorway's opening, John juggles agricultural experiments meant to reclaim tainted land and stretch the valley's food supply, a looming apprenticeship decision for the young Ben, and the responsibilities of an unexplained system counter tied to an approaching apocalypse. When danger reaches nearby settlements, John is drawn from his workshop back into direct combat to protect the people who depend on him.
