Book excerpt: The final novel in the acclaimed Elemental Logic series finds Karis G’deon and her sprawling family once more imperiled, this time by the legacy of violence that threatens to unravel the fragile peace they have woven across their land. Laurie Marks’ Elemental Logic series introduced readers in Fire Logic to the realm of Shaftal, an intricately imagined land whose people operate within the boundaries of their basic natures—here defined as logics—which sometimes bequeath them with access to magical, elemental powers and sometimes embroil them in unsolvable internal conflicts. In Air Logic, Karis and those who love her must figure out, in the aftermath of war and an assassination attempt, how to bring together Sainnites and Shaftali in a country where old wounds and enmities fester and Air magic conceals the treason hidden in the heart of the G’deon’s household. When Medric is taken hostage to force Karis’s hand, a strange boy will guide Zanja to the place where she may yet save him. A mother must remember the son she has been made to forget, and Air children will find what their place in the world may yet be.
