Seraphina has been the Queen of Hell for over a hundred years after purposefully tearing her wings from her back and becoming a Fallen to save her love. When he scorned her, she turned to vengeance against humans for their part in her world unraveling. For years she had sent attacks after the Alliance of Silver and Steam hoping to stop them so she could finally invade the world above Hell. When she spends too much time with her prisoner, Kellan, her mind becomes jumbled and when fate intervenes she quickly loses control of her priorities. Kellan Doughlas had been a prisoner in Hell for over a year. He'd been kept alive on Fallen blood and the addiction to it would kill him and his friends. The real issue was who had been feeding him - Seraphina. Along with an addiction for her blood she left him with longing and desire for her, one that infuriated him because he should only hate her. Unable to stop himself he flees the guild and goes to Hell to try and kill her. When Seraphina and Kellan collide a second time, both are prey to a fated event that they cannot undo. But laying down her weapons and leaving the fight isn't easy for Seraphina, and Kellan has no desire to join her side. Humans had taken so much from her, and demons had taken so much from him. One person wasn't enough to change their futures. When their passion ignites Seraphina's army of Fallen take matters into their own hands to end the long war. They must make a choice, their forbidden connection or their people.
