Vlog brothers

I'm a big Vlog Brothers fan. I haven't actually read any of the literary work of John or Hank Green though. Well recently I found The Fault in Our Stars in a pile of books destined for the trash and started reading it. Actually, I saw a copy of Looking for Alaska recently too at a goodwill in Hailey, Idaho. I thought about buying it, but it was clearly a Sun Valley public library book and it had no sign it was properly decommissioned. I declined the quest to return said book, figuring it would be too troublesome. Anyways, I was reading The Fault in Our Stars and ran into a question. Also, minor spoiler alert. Nothing big I think. The main character, Hazel, writes fictitious author in the book asking about events that take place after the conclusion of the book. The author responds and basically says he will tell her.

Is this what happens? Can this be done?

If I was in the same situation, you know as a writer of fiction (which I’m really not), I think I would decline. The book ends where it ends and what happens beyond that is up to your imagination. You can decide how the rest of the story goes after the book ends, and no one's post-conclusion narrative is any more valid than anyone else's. Even the author’s. That's just what I think the answer is.

OK and slightly larger spoiler alert (but still not really), but as the story continues the response makes more sense. I think in general the question still holds. What do you think?

Small additional spoiler:

After finishing the book, I am more satisfied with what happens in the book. However, I think the question is still valid in general. What do you think?
