In this gripping follow-up to Melissa Marr's lush Seven Black Diamonds; Lily and her friends are forced to reckon with the truth of their own lineage and to protect one of their own; no matter what-or who-comes between them. Now that Lilywhite Abernathy is the heir to the Hidden Lands; everything is about to change. The Queen of Blood and Rage wants Lily to help broker peace with the human world; but Lily knows that harmony won't come easily. After decades of waging war on the humans; who cost the queen her firstborn daughter; the fae are struggling to accept Lily; a half-human monarch. And the humans; while no match against faery affinities; will hardly agree to the queen's detente without resistance. Lily wants to be a fair ruler but fears having to abandon the life she's known. Now that she and Creed are more than just fellow Black Diamonds-operatives for the queen-her priorities have shifted. But her worries about assuming the throne are derailed when it becomes clear that someone-or some fae-is masterminding violent attacks to discourage peace. Who can end the war between humans and fae?
