For what it's worth, Mike Licona recently plugged a book on NDEs. Here's the plug:
And here's the book:
Titus Rivas, Anny Dirven, & Rudolf Smit, The Self Does Not Die: Verified Paranormal Phenomena from Near-Death Experiences (International Association for Near-Death Studies, 2016).
Rivas is a New Age figure. This presents a common dilemma in paranormal studies. Because "mainstream" scholarship generally ignores the topic, investigation is often relegated to quacks and debunkers. However, Licona is not a flake, so the fact that he recommends this book counts for something. Presumably, the value of the book, if any, lies in the collection of case studies rather than the editorial viewpoint of the authors.
