Rene Hemlock, a descendant of a fallen angel, has been forbidden to earth with the mission to make the 'world perfect' by killing murderers, rapist and those who break the law for the rest of eternity, as a punishment for her parents actions. All if going well til hell breaks loose...literally. Demons begin to roam the streets of London. With the devil himself walking among them in human form, Rene has a new mission...

Ever since the falling, Angels have walked among humans, but not in harmony. Destruction and bloodshed wherever they go, the fallen are finished with being humanity's protectors. Armed with three daggers and angel poison, Keira has dedicated her life to eliminating the fallen and their soul devouring ghallows. Life has never been simple for Keira, but what happens when forbidden love comes into play and new secrets emerge revealing truths that make Keira question which side she is really on.
