Ascent from Darkness

I recently read Ascent from Darkness by Michael Leehan.  I thought it was very inspirational and dark.  It told the story of a man that sold his soul to Satan and then had to come back from it, finding God in the process.  I was born a Christian, so to read about a man that turned his back on all of the things I believed in was really hard.  However, when I finished reading, and got to the parts about finding God, I felt all of the things I feel every time I think about my religion.  I felt that I should work harder to be a better Christian just like Michael became.
