A truly perfect wrap up of this particular five-book story arc. So much happens in this book, and I was a bit concerned it wouldn't be possible to wrap it up satisfactorily, but Sutherland did an excellent job providing an appropriate and unexpectedly moving end. My eyes leaked a bit.

There are so many excellent characters here. I really love Qibli and Kinkaju, and it was wonderful to see them shine. This particular book explores some complex (and unhealthy) family dynamics, sticky morality questions, and the question of what is a soul (and what makes us good or evil). The parallels Qibli sees are perfect and help us see that there's a lot more gray than there is black and white.

My recommendation for reading order of the Wings of Fire (WoF) series:
WoF #1-5
WoF Legends - Darkstalker
WoF #6-14
WoF Legends - Dragonslayer (this could be read after book #5, but that would spoil a sweet surprise present in book #14)

The WoF books follow a five book plot arc (with each book covering the growth arc of one character). If book 1 doesn't work for you, consider starting with book 6 or 11 to get invested in the world. Each book adds to the complexity of culture and history in the world, so you may miss a little if you skip books, but the overall plot and story will work.
