The Lunar Chronicles are very fun books. I love the premise of sci-fi fairy tales! Placing these classic, familiar stories in a dystopian future is interesting and adds a neat dynamic to reading as I was invested in the characters and story in their own right, but also I wanted to see what the next parallels would be! Cress is probably my favourite so far of the series. I really like how we have now fleshed out to an emsemble cast but also that the previous characters have not been totally left out of later books. It's a nice balance. I was not completely sold on the core romance of this one, but it is fun and it definitely gets healthier as the book progresses. Basically, I just want these crazy kids to work it out, solve the problem of the ridiculously overpowered Moon People and the hugely deadly plague, and all live happily ever after with their various crushes. 
(I try not to say this about every book, but one of my big gripes about this is it could benefit from being much much gayer.)
