Query: A blessing to read

This book literally changed my life, and two of the best selling Christian novels in history, now combined. The battle raging in the spiritual realm has changed my prayer life forever. With this Present Darkness, Peretti broke onto the scene by graphically tearing back the veil between the human and the spirit world. Descending upon the small town of Ashton, angels, demons, and strongmen engage in a vivid battle and we, the reader, see it all unfold. Before Frank Peretti I wasn't interested in "Christian fiction". I just didn't see the point. But, I love fiction and I love the Lord. It's wonderful to be able to read, enjoy what I'm reading and learn something all at the same time.
