I have loved this series since I read Bitten many years ago. I don't love all the characters/narrators. I don't even love all the books. Some were much better than others. Part of that might be because of whether I like the narrator of the book. Living with the Dead is probably my least favorite book of the series. Part of that is that the entire book is written in third person (unlike the rest of the series) and that it jumps point of views very frequently. The flow was not as good.
With that being said, in this book, Savannah is the narrator for most of this book. When it does change perspectives, it jumps to third person, but in this book it flowed much better. I didn't have the same issues that I had with Living with the Dead. It gave us one last chance to be with our old favorite narrators.
You get to see every major character and most of the secondary characters (though, I don't think I could tell you who is missing that is still alive, but I'm sure there is someone). Also, you get to see several characters you don't expect to see again. Jaz is one. The Cortezes use his unique talents for a mission. The other I won't mention because it is a HUGE spoiler.
As much as I'm saddened to see this series end, I think it was a very good end. Sometimes series fall flat at the end of the series. You feel like you've been building up to this huge finally, and then the end sucks and you're left unhappy. That is not the case with this. I think it ended really well. It is not perfect. There are still dangers out there, but it has a conclusion.
Also, my understanding is that there will still be some short stories from this series. I hope we get to see more from the men's perspective. I loved Men of the Otherworld. It is one of my all-time favorite books. The audiobook for that is even better.
