Anna is an aspiring writer who has an incurable obsession with Doctor Who. When she is not writing about Doctor Who, she's watching favorite episodes and contemplating what to write next. When she's writing about Doctor Who, she anticipates her reward: watching yet another Doctor Who episode. She also manages to read science fiction (especially Ray Bradbury), recite lines from Shakespeare's Macbeth, and make terrible puns in her free time (she likes to imagine she has great puntential, though)
