Seven Black Diamonds

Melissa Marr, New York Times bestselling author of the Wicked Lovely series, returns to the ethereal and bloodthirsty world of faery in this dramatic story of the precarious space between two worlds-and the people who must thrive there. Lilywhite Abernathy is a criminal-she's half human, half fae, and since the time before she was born her very blood has been illegal. A war has been raging between humans and faeries, and the Queen of Blood and Rage, ruler of the fae courts, wants to avenge the tragic death of her heir due to the actions of reckless humans.
Lily's father has always shielded her from the truth, but when she's sent to the prestigious St. Columba's school, she's delivered straight into the arms of a fae Sleeper cell-the Black Diamonds. The Diamonds are planted in the human world as the sons and daughters of the most influential families, and tasked with destroying it from within. Against her will, Lilywhite's been chosen to join them .
