"Does one reincarnate instantaneously or slowly, over a long period of time? Can other living beings, like animals, reincarnate in human bodies? Can man appear as an animal? If so, how and why? Do we reincarnate forever, or does it end somewhere? ... What is the relationship between karma and reincarnation? 'Coming Back' fully answers these questions, because it scientifically explains the true nature of reincarnation." - From the Preface
