I've never found a book that does this, so it would be nice to read one. For example only, It starts with a boy who is bound to a wheel chair and is only able to travel in spiritual form so he travels the universe but gets too close to the sun that it burns the umbilical cord that is connected to his body The story shifts to the boy as an adult lamenting on this and telling it to a friend. The story shifts back to the boy's spirit meeting another spirit who is a female and he asks her name right before the story shift again. It cuts to the boy barely being born and something meaningful is revealed about his physical condition as a female spirit watches. The story then shift to him asking her for her name and she is revealed to be the spirit that watched him being born and she is lost. In the end, he brings her to heaven but is sent into his mortal body where he could now walk. It seems like a very genius idea to write like that style. What is it called? And what are some books like that?
