I really wish the Lightbringer books didn't keep undercutting themselves, because I wish I could recommend them. There is at least one substantial plotline that turns out to be entirely misleading (unreliable narrator, except the narrator is the 3rd person limited variety) to the point I now skip the scenes during rereads.
And then there are a ton of worldbuilding details that get withheld until the last book, major questions that have been asked from the very beginning, which end up delivered with "I guess I need to tell you these things now". But because there are so many of them, a lot of them are underconsidered (in terms of consequences), under-explained, overcomplicated, and underwhelming. The final book in the series has tons of action, but there is much less character work in the action because we've already gone through most of the character arcs.
I still enjoy books 1-4 a lot! And book 5 isn't terrible, but it's by far the longest one (375k words and 25% longer than the next-longest), and it is disappointing enough that makes me hesitant to recommend the entire 1.3M word series.
Minor (vague) spoilers below.
