Benevolent Passion (Heaven's Heart Series #2) by Amanda Pillar

I don't usually read angels books, because of my views on angels and demons. This story is actually about love and purity of heart. It also suggests that there is procreation among angels and demons. The consequences of such actions are also explained. God even has prophecies for such actions. This story is actually quite humorous and I liked Peony and Dru, because of their uniqueness.
