Like any teenagers, the face of One Teen Story is changing fast. Just a year old, the monthly magazine of short fiction for young people is getting a new editor-in-chief:Patrick Ryan, 47 , the associate editor of Granta from 2009 to 2013. He left the London-based literary journal last month. Editing One Teen Story—the younger sibling(姊妹篇)of One Story magazine—will offer Ryan a chance to reach a whole new audience. "Its really the only magazine for young adult short fiction, " he says from his office in New York. " Its tremendously exciting that there are younger people out there who have subscriptions and look forward to getting these stories once a month. That form. is usually only presented when its forced upon them in schools. " Designed for readers 14 and up, One Teen Story publishes nine issues a year. Like its sibling magazine, it doesnt carry photographs or advertising. Its just exactly what it says: one story per issue. Ryan says young people are "looking for engaging reads about people whom they can identify with. Its not about having a message or positive spin(说教). It always starts on a character level, and it has to have an interesting story. If you look at the Twilight characters and the Harry Potter characters, they feel very contemporary. " Ryan also sees the magazine as a way to encourage talented authors. "I would love to make One Teen Story the first publication for writers who then go on and keep at this business. I just really love the idea that this magazine would be the starting point for somebody—would be the push to make a talented writer feel that it was worth keeping at this. "
