This was fantastic. I absolutely loved it. 

The concept of Skyward fascinated me from the first moment I heard of it, and the execution did not disappoint. The worldbuilding is great, the author and artist clearly thought hard about how life would work in low gravity (they didn't answer all of the questions I thought of but that would probably be impossible!). I was invested in the plot from early on. As for the art, it is absolutely stunning - I rarely look at a comic and go "wow" but I did here. 

The hardback edition I read is beautiful (if heavy!). It contains all 15 issues, as well as a new epilogue and some bonus material including concept art. 

I honestly can't recommend this book enough.
