Thanks!
I finished
Holy Sister last night, and wow. Just wow

You all know my feelings about "Red Sister" the first time I read it, that it was just a good book, but that's because I was heavily skewered by Mark's previous 2 trilogies, and what he did with this one, particularly in the first book, was very much different.
Re-reading it now, 2 years later, followed by the other 2 books, completely revised my opinion, and this is very much a superb trilogy in its own right.
And yes, I did see echoes of
Broken Empire in these last 2 books, especially the last one, so please trust me and if you shared my opinion on Red Sister, go ahead and re-read it, and the others, now!
