This is the concluding novel of the Women of the Otherworld series, and wraps up the Savannah Levine trilogy that started with Waking the Witch. Overall, I think it was a very fitting ending, though I don't think Savannah is really one of my favorite narrators. That honor would be reserved for Elena, Eve and Jaime. Still, it makes sense that the novel would end with Savannah as she is the middle between the next generation of women and the ones that made up the majority of the series.
The world of this series was so large and developed that were was no way Armstrong could have truly wrapped up everything, and she doesn't. While the main case of this trilogy is concluded, and the characters all face the threat of supernatural exposure, there is so much more left open, basically treating this as yet another novel in the series, with slighlty larger stakes, and a grown up and adult Savannah at the end who has finally realized it is time to move on and become her own person, no longer quite so reliant on others or so self-indulgent.
There are still plenty of questions about the future, including Lucas and the Cabal, and just life in general. I'm sure Armstrong needed a break from the series after ten years, and this works. It basically shows that all the characters are going to keep fighting the good fight. While Savannah is the main narrator of this, each previous narrator gets a chapter from her perspective thrown in, which is nice. I also enjoyed how one previously dead character's fate ends up being different from what had been thought, and would love to see where that ended up! In fact, I would definitely enjoy it if Armstrong ever returned to this world, maybe fast forwarded ten or fifteen years when the twins are adults. While not every novel in the series is great, the majority of them are rather entertaining, and I can definitely recommend the series as a whole. I gave up on Sookie Stackhouse over halfway through, but this one has kept my interest the entire time.
