Jana, 39, ungeküsst: Eine wahre, mutmachende Geschichte

Okay, so my german was not quite good enough to read this without a dictionary or Google translate to hand and I had never heard of the author before finding this book in my library (don't know how well known she is outside of Germany), but it was a really, as the title says, encouraging story. A story of how one person overcame her insecurities (and eating disorder) and learned to see and love herself for her.
The author has apparently been very open about her eating disorder on Instagram and has a huge following and has been to countless schools throughout Germany talking about eating disorders, body shaming etc. all in an effort to break taboos around these things and help young people so maybe they won't have to live a life similar to hers.
