I'm going to be completely honest - if you have stumbled across this book by chance on Amazon, stop right now. Do not attempt to read this book without at least reading the preceding two books in the Kingdom of Serpent trilogy (Jack of Ravens and The Burning Man), or else you will miss out on a wealth of understanding.
As for this book... It is the last in a well loved (to me, at least) series. And it is a beautiful end. Although the beginning felt a little bit jumbled as it struggles to keep up with jumping between worlds and times and narrators, soon it settles down. The story is fast paced, yet still rich in detail as we have come to expect from Chadbourn.
This is about the last stand of all the Gods that ever existed throughout mythology. I was being introduced to Gods I'd never heard of, and some I'd come across in my travels, and here they were all woven together into the same intricate story line, with a few of our old favourite humans from previous books in there as well.
I don't want to go into too much detail here, for fear of ruining the story. It is Existence's last chance to avoid the mundane-ness of a world without magic which The Void is attempting to bring about. And for the heroes of Existence, the Brothers and Sisters of Dragons, the odds are not looking good. Gods corrupted by The Void trick them and attempt to stop them at every turn, but can they even trust themselves? Or will they be betrayed from within?
Everything hangs in the balance and even in the penultimate chapter, I really had no idea which way it was going to turn out. Exquisitely written, steeped in the kind of detail scholars spend lifetimes trying to amass. Chadbourn is a first class fantasy writer, a complete storm of fresh air to really wake you up.
(Read Chadbourn's books in order - Start with the Age of Misrule Trilogy (World's End, Darkest Hour, and Always Forever), then the Dark Age Trilogy (Devil in Green, Queen of Sinister, and Hounds of Avalon), then the Kingdom of Serpent trilogy. Although each trilogy can be read as a stand-alone, it is much more rewarding to read them all).
