This was a good read. Not what I was expecting (I was expecting a romance as I'd heard it was a sci fi romance), but that's not a bad thing. It reminded me of some of my favorite UF series, but with space travel, tech gadgets and genetic mutations instead of vamps and witches. There were some romance-y bits, but if you are looking for steam then you will be disappointed.I liked the main characters (and Cat is a very intriguing secondary character), but there were so many (almost) nameless secondary/tertiary characters that I got some of them confused. It's also not done - I need to get the next book!
