I like Rachel Aaron a lot. Her DFZ series are all very good. I haven’t written a review on one of the series, but I did read it. Oh “darn,” I guess I need to go read it again so I can give it the review it deserves.
So the latest in the series is the DFZ Changeling Series, which begins with

I will say, I like this protagonist for a lot of reasons and she drove me utterly insane for other reasons. There is a distinct lack of curiosity in her which I find very difficult to grasp. I recognize it’s an uncommon trait in humans…. still! ARG. So, you know, she’s a normal person and it bothers me. Well, sort of normal. Not normal in a real-world way, but not-not-normal in the DFZ world.
I think the best part of Aaron’s books is how the DFZ is the central location for the books, but the whole world feels very real. The protagonist doesn’t need to go to Paris for me to believe there are people there doing their own thing. This series has some of the weakest of this element, but largely because of the impact on the world they are all having. The whole world is being impacted in very real ways, but the everything is happening in the DFZ.
I left the series with questions, but none of them plot- or character-breaking. Questions like “what happens if a fairy goes on a TV show?” and “Are the burrows another plane of existence like the plane of magic, another dimension, or some kind of black-hole-magical-thing with more size inside than outside? Are they physically located somewhere (maybe?) and if so how can there be SO MUCH SPACE?” and “did Victor kill all his victims to make sure they couldn’t talk about his evil actions?”
Basically -Rachel Aaron is always worth reading and this series was no different.
