War is ravaging the Seven Heavens. Lucifer and his Commoner supporters, the lowest class of angels, are rebelling against God’s plan to exile them to the new Earth. When Lucifer departs on a desperate war mission, he leaves his daughter, Evangeline, to defend their home in First Heaven. Fiercely loyal and trained to fight, Evangeline stands ready to do her father’s bidding. But things change when Evangeline overhears the archangel Gabriel forming a plan to destroy Lucifer—because, as he tells his son, Michael, he believes Lucifer’s plan is to find the Key to the Kingdom and claim the power of God to control all the Heavens for eternity. Refusing to believe her father capable of such treachery, Evangeline sets off to alert her father. As she battles through the Heavens, however, Evangeline is shocked to discover that what she believed she knew about her father might not be true after all. For the first time in her life, she begins to question whether or not her father’s motives are pure. With the fate of the Heavens hanging in the balance, she must decide who she’s going to be: her father’s daughter, or her own person.
