Alchemy of a Witch-Part One: Calcination and Dissolution by April Aasheim

As plague rages across neighboring villages, wise-woman, Almara, is arrested for witchcraft. Before she is taken away, Almara tasks her daughter, Morgan, with guardianship of two precious heirlooms.
When Morgan herself is accused of witchcraft, she becomes a fugitive from her own village. Escaping with only her Mother’s strange book and stone, she disappears into The Great Forest, and the rumored beasts that reside within.
