For about the first half of this I was not impressed at all. The book, in my judgement, plummeted right down to two stars because it was just a lot of repackaged correspondence from certain case studies, bearing little real indication of reliability. Not to be all sceptical towards a subject I in no way reject and indeed invest deep hope in, but the supposed evidence presented was nothing more than purely anecdotal. Furthermore, it wasn't even that compelling as all the stories just repeated, numerous times, the same basic events, which did not necessitate so much retelling when most people interested in this subject would have heard it all multiple times before. Simply reporting the same experiences over and over again, without much analysis, made for a hardly satisfying read.
The latter half of the book is much better though. Finally, Dr. Moody goes beyond the basic reporting of personal testimonies, and actually analyses, reflects upon and explores the implications of near-death, or temporary-death experiences. He even goes a long way in linking his conclusions (speculative though they ultimately must be) to historical perspectives on the afterlife.
Overall, while this book isn't necessarily the best on the subject out there - especially as it was published in the 1980s - it is a decent book, with enough of quite exceptional value, thanks largely to Moody's clarity of writing, to justify reading it if you happen upon it and are concerned or curious about what awaits us after death.
I picked this up because I was going through a really strange but crippling emotional fixation over dying in the weeks before. As I still am sometimes when I allow myself to linger on the subject too long, or else am trigged by something in a book or movie, I was particularly disturbed by a sense of my own mortality, as well as my wife's, and I was profoundly upset by the fearful notion of being separated (though, God willing, only temporarily) by a fatal sickness one day in the future, which I can only hope to God will never happen, at least until we have grown old together. Since marrying my wife, and now having a child too, I have more to lose than I'd ever imagined I could, and the inevitability of death, even with my faith, is often an upsetting prospect to contemplate.
To be honest, this book doesn't entirely offer a cure to such existential fears as that. While written by a Christian (Methodist, I think he said), the book does not aim to affirm any particular interpretation or religious belief of what awaits us after death. It merely puts forward the argument that we don't just cease to exist, as atheists would have you believe.
You will probably take out of this book, the beliefs you held going into it. I don't imagine it will necessarily convince anyone who rejects the afterlife to do any more than briefly wonder. And it does not contradict what Christians such as myself believe, apart from a few, weird stories I think can probably just be chalked up to the experiencer being confused.
