Agnes wakes up one morning to find herself the most wanted human by every supernatural being out there but she doesn't know why. Now she must solve the puzzle before the hurlyburly of her new life ends up killing her.
Za'afiel is an Angel of Destruction with domain over storms. It is also known as one of God's personal smiting Angels. Don't get on its bad side.
Kezef is another Angel of Destruction as well as an Angel of Death.
Af is also another Angel of Destruction as well as a "Prince of Wrath." (Now that's a name for a metal band if I have ever seen one.) It is also known as a "ruler of Death over mortals." Which I guess is a power up on the whole Angel of Death gig.
And Raziel is said to be the personification of "Divine Wisdom." He is also an Archangel, sharing magic amongst the mortals. Think Gandalf. Not a war dog but a book worm. Still as an Angel, bloody deadly.
