First 3 books were pretty good. 4th takes a strange turn, with MC making choices that aren’t as well reasoned, in contrast to the previous books. This one just doesn’t have any urgency, all world building and the pace of the book gets affected. MC is still interesting and a few details on WB are noteworthy, but overall this is the worst book of the series by a significant margin. Would I continue the series after this? Only if I had an extra credit and I didn’t know what to get.
