It is like those director's cut DVDs lapped up by hard core fans. If you have read any Marquez book, then you can identify the roots of the story in his biography Living to tell the tale.
It is a typical Marquez book, moving back and forth in time like his fiction. He lets you into how he became a writer, his awful spelling, his influences ranging from Faulkner to Kafka. Marquez's books rise to a crescendo and suddenly drop to a lull. He is the master of varying the pace of the story. The same thing happens in his autobiography too, especially the days after the murder of the Liberal Party candidate Gaitan during Columbian elections of 1948.
It is a refreshing read, a must for any Marquez fan.
