I got this book after a typed "reincarnation" into the search bar. It appealed to me since I'm a romantic at heart and the idea of having someone who is your soulmate who you meet life after life is so thrilling to me. It is such a well written book, the story of Elizabeth and Pedro is separated with the author's thoughts or experiences of other patients the most touching of these occurs at the bottom of page 43. It keeps you on the edge of your seat, because you are not sure how Elizabeth and Pedro are connected or even if they will fulfill their destiny.
I guess the main effect is it really makes you think - am I connected to those people around me? have I already met my soulmate? Is the one I'm with the one I'm meant to be with? It makes you believe in destiny, but explains things I feel comforted to know. For example he suggests that you don't meet your soulmate in every life, sometimes they're not your sexual partner, but your sibling, child or parent, or even if you do meet them that they might not recognise you. It does not contain any trite promises that you will meet your soulmate and he/she will be your husband/wife.
I have not read any of his other books, but I intend too. I couldn't put it down, and read it in one sitting. I think you'll find it more interesting if you believe in past lives or are aware of your spiritually in some sense. But I think everyone would find something of value in this book.
