I just finished another book. Piercing the Darkness by Frank Peretti. It was riveting from beginning to end, and I couldn't put it down. One thing I find when I read his books, however, is that because of a lot of reference to the demonic, it can tend to cause me to have weird dreams and then I start looking around every bush and corner for a demon. (not quite that extreme, but you get the idea.)
It was a great read, and I really enjoyed how it all tied together in the end. If you enjoy suspense type novels, this is a great one.
