The book contains 4 major chapters: BOOK 1: Why do we need to study Reincarnation - the last and greatest mystery of our lives; BOOK 2: scientific and medical proofs for Reincarnation and NDE (near death experiences); BOOK 3: An exposition (treatise) on reincarnation as viewed by various religions and lay people; BOOK 4: A complete- length science fiction novel on Reincarnation. The SF novel describes the attempt of reincarnated persons to find an earth-like planet to settle because god does not let the mystery of reincarnation become known to "earthies" when they are still alive.
