I've had Miss Invisible on my to-be-read pile for a while now. It has a copy right of 2007. But after reading Invisible about the older lady who felt the world wasn't seeing her any longer, I decided to read Miss Invisible, about a large woman who felt the world looked through her.
Genre-wise this is Women's Fiction with a side dish of romance. Spiritual-wise it's all about learning to be comfortable in your own skin, size 6, size 16, or whatever. It's written in first person, but Fredericka Heinz has a fun voice and a dry wit, especially about her eating habits.
Miss Invisible also has an enjoyable cast of supporting characters, the awful and not quite as awful in her dad and her boss, and the mixed bag of friends and potential love interests, and the awesome new friend, who helps Freddie take her first steps to change her life into a more acceptable place.
You probably won't find Miss Invisible in a book store any time soon, but if you find in Ollies, you'll probably want to pick it up.
