This book is JUST A GEM. The REVEALS in this second book in the series are WHEW so WHEW!

Azura is living and she's no longer trapped! Caiden/Winn is the perfect Graven being ahhhhh!!!! Ksiñe being taken by the Prime at the end and his scientific knowledge being used abusively - which will come back to bite our protagonists in the butt, of course

. This novel is just so SMART dammit. It's flawlessly planned and executed in the unfolding of the story arc, perfect found family themes (one of my favorite SF themes in particular), this shit warms my cold black little heart. 

The ending... so much in the ending...! I will be anxiously awaiting Ethera Grave out in March!
