I am asking for a friend. They want to document things and write a book about caring for their father who has cognitive decline. She wants to make the book short but still meaningful. Her hope is to help other people out there who are in similar shoes to her and caring for a loved one who has Alzheimer's or Dementia. What would be a good length for a shorter novel for this kind of topic?
I think 100-200 pages is the max limit for something I would consider a "short novel", Even 200 is a bit too high for me.
