“This book is broken into two main parts. The first covers a period of Victorian England and the paranormal researchers in that period who were trying to prove that something continues after death by contact with the dead in some spiritual realm. The second was mostly about communism and the scientific state. It was only the last 30 pages titled "Sweet Mortality" where Gray really gets deep into the subject matter and then it is too short.
Here's the thing. Gray obviously has a powerful grasp of his subject matter and I found the historical analysis and ideas engaging and interesting. The problem was the vast majority of the text was historical and not the analysis of immortality that I was expecting.
So for what it is, it is pretty good. However I would warn prospective buyers to be careful. You don't get really much of a critic of the current scientific search for immortality. It is there a bit, but not much. ”
