I had loved Dark Matter by this author, and was fully expecting to like this one ... but it just wasn't happening for me. I never really got into the storyline or cared about the characters. 

Told in first person - mostly past tense, but slipped into present tense a few times (memories, reliving them? At the end, current time ...) Covered a bit of time, jumping ahead a year, then more.

It felt a bit preachy to me at times - the whole climate change, humans being a blight. Could make for some interesting discussions though. There were some "bookclub" questions at the end, but they didn't really cover what I thought was worth discussing. For me, it was interesting to "upgrade" someone, make them "better" ... what IS better? More intelligent? More attractive (ala [book:The Uglies Trilogy|493455] - who determines what the basis of beauty is?), physical abilities? What does more intelligence do? Is it a "fix" or do people still have different perspectives? Is there one "right" way?  There were quite a few quotes saved by other users that are discussion worthy ...

Lots of science talk too ... there was a lot I recognized from school study or other books, and other stuff that I had absolutely no idea about.

There was proFanity (x28). No sex that I recall, some violence and "end of the world" devastation.
