A born vampire and therefore not the most mental stable of creatures, the hero turns the heroine for the purpose of using her to infiltrate his fathers group. The heroine, born to a crack head mother and contracting HIV as a child due to dirty needles has had a very hard human life but identifies herself with the hero who's an outcast and a feared creature with seriously parents issues. The hero is not a typical good guy. He is a Killer meaning he's taking human life to quench his thirst and he has a very unhealthy amount of rage inside but slowly as the book goes on you realize he's not all bad. He doesn't kill the Guardians though he very easily can-partly because of a promise made to his fledging and partly because he has a soul. He kills bad people-kind of like Dexter. The heroine is an innocence and despite her hard life she's compassionate and kind hearted. A virgin in mind only because of the gang rape that took place is the previous book, the hero takes her emotions about the incidence so she remembers it happening but is able to go forward with a healthy sex drive, something she couldn't have done otherwise.

Gabriel, who had made his appearance first at the "Secrets in the shadows"; is one of the main figures in this book.
Filled with rage ,he comes to Philadelphia to take revenge on his father. But things go out of hand when he falls for his young fledgling and the link between them shows unusual attributes.
Shadows on the soul is by no means original and despite the fact that, the main characters are vampires, it cannot be classified as a thriller. However,it can make a light and entertaining read; suitable to kill time in waiting rooms, on public transport or during breaks. ( )
