Main Character is a young, teenage girl. She herself is not a natural, but she can act the part fairly well, does so, and there may or may not be a love interest in this book. Later she goes to a camp of sorts, for rock climbing or some such thing. Meets, well, her twin. They identical in every way. Realizes something screwy is happening, things spiral out of control from there on. It would of been published in ths 90's or early 2000, definitely before 2008.

(view spoiler)[ She and her twin later finds out that they're clones, and since they weren't granted the dubious honor to be cloned, this is a MAJOR crime and now her family is wanted by the government. Eventually threatened/sentenced to be burned or some such thing. Everything ends ok, somehow, can't remember the ending. (hide spoiler)]

There's another query on here with a similar description. The solution for that was Star Split.

Might be it, not sure. I'll mark this as solved for now, as its the closest thing to what I think is what I read.
