Angel of Ashes and Dust: Wormwood Trilogy, Book 3

Kali learned the hard way that her abilities cannot be trusted if they can be used against her. In an effort to protect those she cares about, she is determined to let the power of her Shadow lie dormant, despite the dangers rising up around her. Now, tormented by an unstoppable enemy, she and Tiamat Wormwood must try to lead others while doing the impossible-ensuring the survival of humans and half-angels alike. But how can she partner with Tiamat, when her proximity could kill him? And how can the Nephilim, Tiamat, be trusted to save a planet, if he is the one who shattered it in the first place?
