SPOILERS:
While I liked the tenor of the story, the ending ruined it for me: Houses are burning, trees are turned to ash, rocks are turned to dust, but people aren't bursting into flames? If the author is going there, it requires some sort of explanation, even a weak one. And why choose to kill himself and his sons in that way? I'm sure there could have been easier ways to do it, but then there wouldn't be a story, so I get that. It just felt very contrived. I suppose this sort of story is more about the journey, but it came undone for me at the end. I hope I don't sound too harsh, as I'm trying to give a constructive review. And if I'm missing something, please correct me.
