At the Fallen Academy, they believe that Brielle is dead. But in reality, Lucifer holds her captive in the underworld, intending to use the girl in his terrifying scheme: to fling open the gates of Heaven and deal with the archangels. For the sake of the safety of those she loves, Brielle agrees to the terms of a deal with the devil.
But she has no intention of giving up. After several months, Brielle manages to escape from hell with the help of a dark mage. Almost as soon as she gets a faint chance to see the people dear to her again, she learns that Lincoln—the love of her life—has vanished without a trace. To get him back, Brielle is ready for anything—even to go back… to the City of Demons.
