Really? Could you list some pro's and con's without giving away any major spoilers?
Basicly shes the state police in the Imperium of Man, and deals with inner corruption, heresy and treasons, which puts her in some of the most complex webs of intrigue. Its as i can go without going into spoilers. Hope it helps.
Thanks 
And she is a strong character with a good arc through three books. It's refreshing reading a book with a female lead that isn't "herp derp I need men to do everything for me because I am weak and don't know what to do hurr".
