This is my idea of what one of the characters should look like.. The House of Night.. Kalona - Kalona is a fallen angel, an old warrior of Nyx,that first appears in "Untamed" and is described to have the appearance of an angel. He has beauty beyond compare, wings the color of the ravens wings (dark purple), long, thick black hair, and the ability to change into the form of a giant raven. He has smooth skin the color of the sun's rays and his eyes are the color of amber.Since Kalona was a creature from the heavens, he has an aversion to earth and prefers to not go under ground unless completely necessary . The books are by P.C. and Kristin Cast, a Mother and Daughter team- I read the complete series ( 7 books so far) and I enjoyed them very much..
