Hmm u forgot to tell him the name of the book. It's called Radnomaden. The homepage is called
www.radnomaden.de and on the homepage u can find this pic of her.
The book is really good and in the book is a pic of her in her cycling clothes as well (different to this one but similar). When i read the part about iran, i think it was just important that she dont looks too feminine.
