This book is fan service for those who liked the series. (I think they’d be easy enough to get into if you hadn’t read the Lunar Chronicles.) It’s a lot of the same stuff as in the books - saving the world, kick-ass-ery, romantic tension, etc. You know.

That being said, I enjoyed this more than I expected to. And I have a soft spot for AI characters who are more human than you’d think their programming would allow them to be.
