Part of me wants to say I liked this a lot more than 3 stars, but parts of this book really annoyed the crap out of me.
Asaro brings the awesome-sciencey fun like she always does with the physics and explanations of physics terms and ideas that I am not terribly knowledgeable in. Her ability to bring complex physics theories and ideas into her books are why I like this series so much.
She didn't have as much political intrigue in this book, which is something else I really enjoy about the Skolian Saga books, but it makes sense that some of the interplay between people/societies wasn't as well developed.
Althor is probably my second least favorite character so far - he is written entirely too inconsistently.
The romance part of the story fell incredibly flat and occasionally creepy (graphic sex between a 17 year old and an almost 50 year old? No thanks). It even got downright annoying, which is why this one doesn't get 4 stars for me. Also, I know the series features a slaver-race/society, but the rapeyness in this book really could be toned down.
It was alright - I did like the later parts of the book a whole lot, and it definitely wasn't as bad as Diamond Star.
