Since we only know the title 'the real megan is missing story', it's difficult to say exactly who Megan is. She might be a young girl from a small town, or a woman living in a big city. Maybe she has a family, friends, and a job that are all affected by her disappearance.
There's not enough information to know exactly who Megan is in'megan is mossing real story'. It could be a common name for a fictional character in a story that is being developed, or perhaps it's a real person that the speaker is familiar with but hasn't provided enough context for others to identify. For example, it could be a Megan from a school project where a real story was expected but is missing.
Maggie Moore in 'Maggie Moore (Based on a True Story)' is the central figure. Given that it's based on a true story, she could be anyone from a small - town hero to a victim of an injustice. Maybe she was a businesswoman trying to make her mark in a male - dominated field, or a mother fighting for her children's rights. Without more information, it's hard to say precisely who she was, but she was clearly someone with a story worth telling.
I'm not sure exactly who Megan is without watching the story in detail. But she's likely a person who has a very high weight and is on a journey to change her life in the context of 'my 600 lb life'.
It's hard to say for sure. It depends on how it was written and presented. Maybe the author drew inspiration from real life but changed some details for the sake of the story.
I haven't come across a novel titled 'Jerusalem Moore' in mainstream literature. However, the name could potentially be used by an indie author. It might be a good idea to search in specialized book databases or small - press catalogs to find out if such a novel exists.
