It has now been more than sixty years since Ariane became a vampire. With her position secure as a member of the Midnight Accords and her fief prosperous, she should be safe and preparing for the future. Unfortunately, her powers are going haywire. Intense bursts of essence are leaving her exhausted. It is time to fulfill her promise to her blood sister Jimena by joining the knights, the only organization that could teach her the discipline she needs to overcome this hurdle. As the guardians of order for vampire-kind, the knights are as powerful as they are dangerous. Their ranks count famed blade masters but also some old enemies. Ariane will have to tread carefully because not even they are immune to politics.
I don't have much to say because the book is great...as usual. There are only so many times one can repeat the same praise before it feels like there is no point. This book continued a long tradition (this is the 8th book of the series!) of being great, filled with exciting conflict, unexpected twists and turns, and wonderful character interactions.
