I don't want validation for my idea or anything. I'm just a little unfamiliar with the liberties writers usually take to write a fictional autobiography. So I wanted to go back and forth in time for each chapter, so for example, chapter 1 will start with my main character in his present writing his own biography and chapter 2 will be him narrating the events of his birth and chapter 3 will be him telling a friend in the present that he's writing an autobiography and chapter 4 will be him narrating the events of him meeting that friend etc. So essentially there are two separate plotlines. Has this kind of thing been done before? Was it done well? What past examples can I read to help me? Would it be jarring and tedious for the reader to read?
