Terrible Means (Ismyre Series Vol. 2)

In the city of Ismyre, something is stirring… An aristocratic businessman reveals the latest must have: a pillar of crystals that when placed within a home allows for the creation of beautiful illusions and more powerful spells to be performed. At the same time, Henriett, a disgraced biological professor now studying botany in a town far away, feels the disquiet in the air as specimens she has studied for years begin inexplicably dying out.
