As good as folks said it was! Both versions of cyberpunk dystopia were relatively believable, and it’s kind of funny how easily I suspended the huge amount of disbelief that the “stub” technology deserves 
Without leaning too hard on many real-world mythical tropes (aside from “things not to do if you visit Faery”), it very much has the feel of something that could have. It’s a short book I devoured in an afternoon and wished for more.
Current:
The Black Company series are where Glen Cook’s best writing is (aside from the really weak Port of Shadows), and most of the rest I’ve tried has just not grabbed me. This one did. Why this omnibus of three novels was named “Darkwar” when there are two other series with that name I don’t know, though it’s a relevant term from the story.
I’m somewhat intrigued by the vaguest hints that this setting might tie in with the Black Company setting. Just a city name and a particular piece of magical technology link them… though really I suspect there’s not supposed to be a connection, and these were just ideas in Cook’s head that he wanted to come back to.
I like the character’s development from frightened and frustrated child to immensely arrogant super-powered scary sorceress… who still has doubts and blind spots and makes mistakes. Sort of a prototype Lady, perhaps.
Also, I wonder if Cook had a really scary, unpredictable grandmother and kept writing her into his novels.
