This is a book I borrowed from the library when I was in junior/senior high.
The plot revolved around a young woman who could use something called a sunstone (not sure if it was one word or two) and is sorta' pathetic, but gets better as she goes. It takes place in space partly, as I remember her being on the bridge of a ship.
Any ideas? Thanks!
Note this is not about Stjepan Sejic's Sunstone series nor Sydney J. Van Scyoc's Sunstone Scrolls series.
