Angel of Darkness (Fallen Angels - Book 5)

Angel of Darkness (Fallen Angels - Book 5)
My name is Frank. I joined the police force to make a difference, but from the first day on the job, everything I've done has made life worse for everyone around me.
For twenty-five years, I searched for meaning, to make sense of my life, but I never found any answers.
Just when I decide to turn my back on my life's work, I uncover a conspiracy more sinister than anything I ever imagined.
As I investigate, I realize that even if I stop the conspirators, the blood of innocents will be on my hands: thousands will die. If I don't stop them, all of mankind will suffer an age of darkness...
