This is a very good study on the subject of demons in the modern world. Much of this book was written with first hand knowledge and is authoratative, yet easy to understand. The book is fast moving and highly informative. It is large enough to encompass it's subject matter without being filled with unnecessary information to increase the page count and the cost of the book.

I recommend this book as a ground level study on this subject, and a must read for anyone who wishes to begin an indepth study on the tactics and abilities of the enemy and how they can be defeated.
