Well, here we are: the finale of The Wicked + The Divine! Unfortunately the Comics Plus app didn't have Volume 9 on it, so I had to snag the physical copy from the library.
I had no idea where the story was going, beyond a few hints from Ananke's sister that the Children would have to find their own way out, and the ending she suggested to Ananke was false. Volume 9 also finally explained how Ananke (and Minerva) worked - Minerva appeared when the other Children's powers appear. They are basically the same person, but their consciousness splits until one of them dies.
I was also really happy to see that reading Volume 8 was necessary: some of the things that happened with earlier pantheons (specifically the last two pantheons) directly came up in this book.
I was really excited that some of the characters who were sidelined earlier by Ananke got new bodies! And Baphomet/Nergal made an amazing sacrifice that no one saw coming (not even the other characters).
Laura Wilson managed to find her way out of the cycle first, at the end of Volume 7: she realized she wasn't a god, but still had her powers. It just took practice to make them work. When everyone confronted Minerva, she was the one who helped everyone end the cycle. It wasn't an exciting climax (in an action way), but it was a very fitting end for the whole series; you don't realize at the beginning how it's about the birth and death of stories, but that's honestly what The Wicked + The Divine is, at its heart. Not only their birth and death, but their power.
After that, the story wraps up with Laura accepting the punishment of her crime for murdering Ananke back in Volume 4. Then the book ends many years later, at the funeral of Cassandra, who comments on the good that the remaining members of the Pantheon have wrought now that they've broken free of the story and were able to live out their lives as themselves, not gods.
All in all, Okay is a fitting end to The Wicked + The Divine. I'm glad I decided to reread/finish the series. While it is often quite brutal (there's a lot of gore, which I found very uncomfortable), the story is good; overall I enjoyed it.
