I've been putting off reviewing this book for a while, trying to come up with something new to contribute to what has become a very large conversation. I don't think I'm going to succeed, but I will add my thoughts. Here's the thing: All the Birds in the Sky very swiftly became the "It" book of 2016, and now in 2017 it is up for All The Awards. Many many people love this book. So when I sat down to read it for my book club I had really high expectations. Did the book rise to meet them? In some ways yes and in other ways no.
I quite liked that a fair amount of this book put fantasy and science fiction into the same world and made them ideologically opposed. We have the young witch and the young mad scientist, and we stick with them as they grow up and the world falls apart. Both the strength and the weakness of the narrative is that at its core this book is really only about two people. If you manage to invest in these two characters and their relationship then you will likely like this book. However, if you want to see an epic battle between science and magic, or you want to focus in on how the world is falling apart, or even the world-building or other characters, well, you are going to be really disappointed.
This is a book that presents a bunch of enormous, epic, sweeping plot points...and then pushes them into the background so they merely serve as the backdrop for a slow-burn romance. Which is honestly something I haven't seen before. I was okay with it, but it was a surprise, and could be really disappointing depending on what you want (or if you strongly dislike the two main characters, which wouldn't be difficult as they can be quite abrasive). The climax of the book felt subtle to me in that the book could have ended in several previous points with equal punch. In many ways it reads like three connected short stories - it has a light touch, close focus, and the bigger plot in the background is overshadowed by a more intimate and close perspective. Again, I didn't particularly mind this, but it was an unexpected choice.
Overall I liked All the Birds in the Sky because I was fine with the soft focus and narrowed plot. The side characters were flat and interchangeable, but that didn't hurt my enjoyment since they were so secondary to the focus. The world-building left a lot of questions unanswered, but again, that wasn't the focus. There were some jarring tonal shifts, and the comedy was occasionally bizarrely executed, but I was having fun so I didn't mind that either. Bottom line, I could see reasons to dislike this book, and problems, but I enjoyed myself and the book despite all of them. There's one thing I'm a stick in the mud about though: there were better fantasy/sci-fi books in 2016. I liked this book. I really did. But it was not the end all be all of books in this genre. Worth the read? Absolutely. Worth the hype? Debatable.
