Ascent from Darkness: How Satan's Soldier Became God's Warrior by Michael Leehan
Michael Leehan tells the story of his life, with a really short glimpse into his childhood and then recounts how he became a devoted satanist surrounded by darkness. He becomes a devoted follower of Satan through rituals and sacrifices. His life is normal in the sight of others, because he lives as everybody else before the eyes of the others: studying, having a job, spending time with his children, etc. This story is really something which makes you think about many things, like the easiness to seduce "christian" women easier than those from a bar, the loss of power of God's people and His church, and so on.
