Is it normal to be a semi-professional author at age 14?
My sister is 14, and she's a semi-professional, beyond-her-years writer. She has written 70,000 odd words, and is working to study for a BA (hons) within the year. She knows everything about literature, words, grammar. And her novel is hitting on touchy subjects such as rape, romance, sex and family abuse - she does so much research, interviews, and all.
I also think her novel is the standard of many great authors, and although being her sis I am a little biased, loads of other people have agreed (people who aren't being biased).
