Master of the Tower: A Story of Witchkind - witchkind, #2

Three years ago, Daniel Scratch ascended to become Adherent of the Sixth Axis, the primary, magical forces of Endings in the world. Since then, he's tried to use that power for the betterment of all witchkind-despite the "don't bother" attitude of the senior adherents of the other four Axes. The other junior adherents, on the other hand, are much more willing to help the rest of witchkind-especially when it comes to curtailing the humans' use of magic-draining iron. But a critical misstep tears the Veil, the subtle, delicate magic that conceals witchkind's true nature from the humans.
Human priests begin calling for a resumption of the Hunts, and the death of all witchkind. To heal the Veil, Daniel must confront his own vulnerabilities, the millennia-old history of his predecessors, and the very nature and reason for his own birth.
