I suggest that "Non-Fiction Books" and "Fiction Books" be given each their own individual subthreads directly under each month's thread (in short that you needn't have a "Books" parent comment connecting the two). There's no need for them to share a parent. It makes the comments look a tiny bit more cluttered than they need to be.
This is a good point. I'll try to remember to do this next month.
