I do love it when a character I 100% vibe with arrives on the scene. I love, as I have said in a few reviews before, incredibly strong, powerful women who are also dumb as a bag of hammers. It just tickles me. And we get that in spades here with Julia, a vampire who’s on the side of the bad guys and actually forces Mercedes to try. See, she’s not only strong, but it seems to be entirely instinctual – she hasn’t been taught anything, but when she sees a move she’s able to work out counters and the like just on her own. And she’s also the funny kind of dumb, which is important. She will fall for them pretending to be on her side and spill all sorts of secrets. The big bad, when their plans inevitably go south, assumes it’s her fault simply because she causes chaos wherever she is. I was so happy she wasn’t killed off.

Things are going pretty well for Mercedes, though she’s still struggling with the whole succession thing. Unfortunately, Sieglinde may be the official princess, but the country does not really want her to rule, especially since the empire next door were all misandrists. So she’s got to get married, and the person who marries her will have all the power. Then Mercedes gets a visit from a guy named Basil, who she notes looks exactly like a typical anime bad guy (he looks a lot like Gin from Bleach, in fact). Basil says that there is, in fact, another royal with a claim to the throne – and he has a dungeon. Sure, he’s a naive ten-year-old who is clearly being set up as a puppet king, but that’s irrelevant – he has a dungeon, and he’s male. How are they going to handle this?

As it turns out, the backstory that led to all this turns out to be rather convoluted, especially since it means that there’s another person with a connection to the royal family. My favorite part of the book was possibly Mercedes’ unreliable narrator moment. To be fair, it’s not without signposts – there are several points where she notes that she’s being too kind or too soft, and we think “wait, back up, Mercedes? Too soft?”. But her father clocks her right away, and instantly lays out her entire thought pattern in three paragraphs. It’s very clear that whenever this series ends (I’m estimating 1 or 2 more books), it’s going to end with Mercedes battling her father for supremacy. In the meantime, congratulations to the country, which now has its royal who can be king, and he’s at least semi-competent. Oh yes, and the little boy who was being manipulated is not killed but put in prison instead. I’m sure that will be FINE.

The 5th volume is not out yet, so get ready to wait. This is a decent little OP cynical vampire series, even if I could have done without hearing about how vampire’s breasts never sag because of their eternal youth (or, in the case of Mercedes, eternal tweenhood).
