内容简介：
Eden and Abdiel are gargoyle knights - hunters of supernatural evil, descended from demons. Time and again they have risked their lives to protect humans from monsters and ritualistic murderers, but now they have been betrayed by one of the very people they fought to protect. When Abdiel is poisoned, Eden will stop at nothing to find a cure. Her search will take her to the halls of the Gormogon Order and into the stronghold of an ancient enemy, as she races against the clock. With her brother's life hanging by a thread and no idea who she can trust, there is no line Eden won't cross to save him.
