Alchemy of a Witch: Part One by April Aasheim

A once peaceful land is besought with unrest, as “The Great Sickness” spreads its malignant vines across towns and villages. Suspicion reigns, as neighbor fears neighbor, and The Church searches for the root of the plague–and a scapegoat.
As the dead accumulate, a verdict is delivered: witchcraft is to blame.
This is the first book in a four-part, stand-alone series,.
