"Sparked by extraordinary experiences that occurred in her family when her father and her sister both died in 2008, Patricia Pearson was launched on a journey of investigation into what she calls 'a curious sort of modern underground--a world beneath the secular world, inhabited by ordinary human beings having extraordinary experiences that they aren't, on the whole, willing to disclose.' Roughly half the bereaved population, about 20% of those near death who recover, and an unreported number of the dying witness or experience a sensed presence, the mystery of near-death awareness, and, if they are not in horrible pain or medicated into unconsciousness, rationally inexplicable feelings of transcendence and grace as they depart on the journey from which none of us return. Pearson brings us effortlessly into her illuminating quest for answers, inspiring us to own up to experiences we may never have shared with anyone. Secular or religious, all of us wonder deeply about these things if we let ourselves, and also about the medical, social and psychological implications of understanding what it means to pass through heaven's door."--From publisher.
