Petra Kyler always feared the Rabenauct, a mysterious kidnapper who stole children away from their homes. Legend said that he would descend upon a town, take one young girl away, and then disappear. To Petra, the Rabenauct was the monster in fairy tales. She never imagined he would bring horror into her own life.
Then, her sister, Layla, disappears.
Petra knows that the Rabenauct took her sister for his twisted games, but how do you hunt down a man who seems to exist only in legend?
She's going to need help.
Petra, now a young woman full of vengeance and anger, enlists the aid of the Pack, a group of unconventional thieves who adopt her into their makeshift family. Their leader, the charming, infuriating Cyrian, takes a shine to Petra. She begins making friends with the others: free-spirited Bell, kindhearted Novu, imperious Victoria, and stoic Harris.
Their hunt will take them to the enormous, dangerous city of Silvertree and into winding catacombs, where death and darkness lurk. Petra is determined to avenge her sister, but the truth about the Rabenauct will shock her to her core. Is she prepared to sacrifice her new friends to avenge her family?
