Having read a lot of books on the subject of NDEs, I purchased this after reading the positive reviews it received. However, I feel that this book will only be helpful to those who have never been exposed to anything but the most mainstream of religious ideas. Some of it is downright offensive -- Tom Sawyer is quite an arrogant character, talking about himself in the 3rd person, and he reflects, apparently proudly judging from the tone, on the days in his life when he frequently kicked people's a**'s and dominated his wife in a manner that is borderline abusive. Furthermore, he makes frequent contradictions of his own message (All religions are valid and God is unconditional love, BUT suicides (and apparently ONLY suicides) go to hell, even if they are retarded and not capable of making good judgments).
Having read a great deal of NDE literature, it seems that Tom, just like many people who experience an NDE, believes that his wonderful experience was THE TRUTH (TM). It's worth noting that almost everyone who has an NDE feels this way, and many of those accounts contradict. I am not saying that I doubt that there is something real going on here. What I think, rather, is that God presents himself in the manner that will be most helpful to each individual person, and the experience of God is so powerful that people come back thinking they have the ONE TRUTH. Tom tries to avoid sounding this way, but it's obvious he feels it -- he claims that he went to Heaven (the real deal) while other NDE'ers who might contradict him just go to Paradise (some lesser Heaven that isn't really the abode of God -- in other words, not as real as his experience).
Also, he makes a lot of predictions about what will happen to the Earth that, of course, never happened - the nuclear apocalypse is about 10 years late, by his reckoning. This is also something a lot of NDE'ers do.
If you're going to read, tread lightly; soak up the message of unconditional love and use your own best judgment when considering the weird/bad stuff.
