I loved this prequel to Shadowed Souls! The author's writing style is excellent and she draws you in with her fast-paced story development.
I connected with the characters right away and was fascinated with the perspective of the story seen through the eyes of Robert Tannery's guardian angel.
First Fall acts as a great prequel to Shadowed Souls because it fills in some interesting background information. It also reads really well as a stand alone story.
Great job, I highly recommend it to anyone interested in urban fanstasy or angels!
