This book is excellent - it forces the reader to re-examine their strict adherence to the world of scientific rationality in which we now live, and opens doors to a world many would never think possible and yet which is vital that we take notice of. Martin provides the stories and details of the possession and excorcism of five people in a straight-forward manner that nonetheless omits nothing.
As a strict believer that the forces of evil are grossly misunderstood and under-studied aspects of out daily lives, I found this book very useful, and would reccommend it to anybody who has a similar interest, to anybody who wishes to learn of true demonic possession, and to anyone foolish enough to believe that good and evil/angels and demons are nothing more than myths or words.
A rivotting read, and definately not one for those of nervous disposition, or those ill prepared to be introduced to evil.
