This is a surprisingly good read. From the book blurb, I expected something a bit campy and silly. Instead, it's a methodical tactical adventure featuring a female mage who gives her all to protect those she cares about. She has limitations that she struggles with, friends who help and hinder, and an enemy who views their actions as being just and right.
If you like fantasy, an interesting take on magic in a world where it has a massive impact on life and combat while also taking its toll on its users, while watching someone who does their best to overcome their obstacles without angst or ire, then enjoy.
