I'm looking for a story I read about whose protagonist (a girl, I think) had a unique ability that anything she wrote with ink on paper would inevitably become true.
Plot points I remember:
- At a few points, she would involuntarily write down a prophecy. One of these prophecies included the line "The bridge behind you washed away".
- At one point, she came into possession of a book that purported to contain information about the future; however, aside from those involuntary prophecies, it was constantly in flux.
- She's being hunted by an evil king who wants her to use her power to secure his rule forever. She's eventually captured and forced to write a prophecy declaring him "king now and forever". However, she uses the loophole that only what she writes on paper becomes true, writing down the prophecy on a piece of paper partially covered in candle wax so that it instead reads "king never", defeating him.
Where and When: I read this serialized in a children's literature magazine, American, about 10-15 years ago.
