In some ways better than the previous book, in others worse. Still suffering from bad writing mixed with unpleasant brutality, though to a lesser extant.
And while the first book was carried by the world building and exploration of some cool concepts, in this one it's not really developed any more.
The ending is better in principle, the "good side" realises they are just as bad (Suzl accepting the spell, Cass retiring from the church and her spell) and the bad side wins for that, even though the battle was lost for them they are set to win the war. However it was also poorly executed and written, like the rest of it.
There are some good elements to the story telling, Spirit's story has parallels to Cass's but isn't just a repeat and her choice at the end is one of the few things that were well written.
Overall the actual rating tends more to 2.5.
So now that I've read this one, since it's been on my shelf years (though of course read digitally now) I'm not sure I will continue with this series. :\
