For a second print, this book has a lot of typo's. I counted over thirty but that isn't a real negative aspect, just surprising.
Some parts of this book seem to contradict itself. I find it strange how Mr. Coleman mentions that spirits are dissapointed when they reach the astral realm because they may have had other religious beliefs and expected a different after life while it makes reference to Christian text and gives examples of prayers to either "Almighty God" or the Archangel Raphael. Another example is that he mentions how you "should" offer hard alcohol in a shot glass while on the next page, he says it's better to serve it in a bowl. Not a huge contradiction but the point is still there which is a bit perplexing.
Other ideas are hard to believe. Such as "Astral Police", not actually police but spirtual authority figures that seem to wield some power over spirits. There is also mention of Guardian spirts patrolling the Astral Realm which again is hard to believe. I'd doubt that a spiritual realm would have relfections of a living society, IE: Authoritive figures to keep order. It also seems unlikely that spirits would eat. For the energy in food can only be extracted by a chemical process. The same goes for giving spirits beverages.
With my "beef" aside, I'd say that this book is a comprehensive guide to the modern/christian approach of Necromancy and if someone is interested in this type of practice and has a magical or spiritual back ground, than this would be a great book for such a person. Although I'm skeptical, I'm still very glad I purchased this book and I enjoyed reading it.

I'd also reccommend this print over the first one as there are certain changes and additions that have been made.
