Angel by T. Ulick

Hell was created by First Angel Lucifer for one reason: To have Gloria, a beautiful Angel girl, for his lustful desires. Knowing that evil, sin, and pain was created so Lucifer can have her, the most beautiful of all Angels, she knows she must be the one to stop Lucifer's madness to have her. Guided by her father, Michael the Archangel, only a young woman she becomes the new Archangel, the true Guardian to all. Vowing to vanquish Lucifer to nothingness, she is majestic as she wields the Blade of Glory and pursues the demon through all eternity, confronting him on the last shard of rock at the edge of all creation. An epic tale of a young girl coming of age, defying her father and God, Gloria draws a line in the sand at the Arch to Heaven declaring that any who do wrong to any other will face her. The Guardian. Their doom.
