Lilywhite Abernathy is a criminal. Her father’s “unconventional” business has meant a life of tightly held secrets, concealed weaponry, and a strict code. But Lily’s crime isn’t being the daughter of a powerful mob boss. Her guilt lies in the other half of her DNA—the part that can coax ancient rumors from stones and summon fire with a thought. Lily is part fae, which is a crime in her world. From the time before she was born, a war has been raging between humanity and fae. The Queen of Blood and Rage, ruler of both the Seelie and Unseelie courts, wants to avenge the tragic death of her heir—a death that was the fault of reckless humans. Lily’s father has shielded her from the repercussions of her ancestry…until she is sent to the prestigious St. Columba’s school, straight into the arms of the Black Diamonds. Mysterious, glamorous, and bound together in their mission but constantly at odds, Zephyr, Creed, Will, Roan, Violet, and Alkamy are a Sleeper cell of fae, planted in the human world to help destroy it from within. With covers as rock stars and celebrity children, the Black Diamonds carry out the queen’s war against humanity. And unbeknownst to Lilywhite, she’s been chosen to join them. Now more than ever, Lily’s heritage puts her in peril, and even the romantic attention of the fae singer Creed Morrison isn’t enough to keep Lily from wanting to run back to the safer world of organized crime. Melissa Marr returns to faery in a dramatic story of the precarious space between two worlds and the people who must thrive there.

Who can end the war between humans and the fae? 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 détente without resistance. Lily wants to be a fair ruler but fears having to abandon the life she’s known to do so. 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. In this follow-up to Melissa Marr’s Seven Black Diamonds, Lily and her friends are forced to reckon with the truth of their own parentage and to protect one of their own, no matter what—or who—comes between them.
