"It is character evaluation through crisis,' I say. 'You cannot take a person’s true measure until they are threatened.”

A Test of Mettle (The Iron Druid Chronicles #3.5) - Kevin Hearne

Cute little story about Granuaile and the help she gave Sonora. One morning she runs into a couple of "old friends" and learns a valuable lesson about herself. It gives you a quick look into Granuaile's life as an apprentice and what she is experiencing while Atticus is away.
