Oh, you're actually reading them in order? That's crazy. Generally they get less tightly edited afte the fourth, but they're still good fun.
I had no idea who Seanan McGuire is, but I just checked out her bibliography and holy **** does she pump out books. Is she perhaps some kind of machine?
I also just finished up the Broken Earth Trilogy by NK Jeminism. They were ok. I loved the storyline - that's what kept me going through three books. The characters and writing were only so-so.
I liked the writing, but if you didn't then definitely don't read her other books because they;re considerably worse. Actually, my one problem with the series is the storytelling, specifically the pacing. Too much of the main character's arc happens in the second book, and so she spends most of the third book not really going anywhere until the ending.
