I devoured this book - after the first one I made myself wait a bit before reading the second, but I just jumped straight into this one. As per usual, this book had great pace, great plot, amazing characters, and a twist in every chapter. My favourite characters were deepened and new awesome ones were introduced (who I love just as much), and I have a great time with the characters in this world. 
 The ending left some things open, but I thought that was nice considering the ongoing theme of hope for the future - it would have been weird to give them their paradise with a nice bow after all this trauma, but it still felt like just enough of a happy ending. 
 (view spoiler)[ I'll come out with it, there was a liiilllll too much goo in the Akiva/Karou romance scenes for me. Give me more Zuze and Mik over flying wackiness any day. (hide spoiler)]
