Is the reason why you dropped the book because
the story becomes about Laconia taking over rather than being about the mysteries of the ringbuilders?
I don't even know about Laconia, I dropped the books after book 5, which was a welcome focus on the characters and inter factional struggles than the alien narrative which I felt was going nowhere in book 4, wich is why I didn't trust the authors to come up with something interesting in that regard. I wonder if pulled that off by now. I read the wiki plot preludes which are very broad but I read about a 30 year gap and some dude who founded an empire which might make things interesting.
