Sanctuary by Caryn Lix
My rating: 4 of 5 stars
Clearly the start of a series (or at least a duology).
While much of this was nothing new (prison for "anomalies" is a space station of sorts, dystopian world with corporate vs. national citizenship, etc.) and the characters pretty static, this was still enjoyable. I particularly liked that the aliens (not really a spoiler - you know there have to be aliens, right?) weren't humanoid.
