How would you describe the Organization of Lehna's Narrative? Chronological? Reverse Chronological? Some other order? Where does the story start and end, and how effective is this structure?

On my opinion, Lehna's Narrative is a non-chronological story that starts with a description of his regrets after being sent to prison and it also presents some flashbacks about his life as a young man and how was it like to live in his hometown. Then, Lehna starts to guide the reader and explains what is the story going to be about. After that, he changes the order of events and starts telling the story in a chronological order, first, the reason and the circumstances of his arrest, then the life in prison and at last, the moment he got out and how people treated him as an ex-convict. I consider the story is very effective because he starts telling he was in prison and that catches' people attention, because he doesn't clearly explain the reasons, so, as a reader you want to know what really happened and how he manage to live after that.
