YA book about a girl who is cloned and the clone does bad things/things she would not want

[Rachel]

A patron at our library is looking for a book he got from the Highland Park Public Library. It is about a girl who is cloned and the clone does things she doesn't want her to do. The most specific thing he remembers is the book cover. There is a picture of a girl running and she is going in two different directions. The top half of her is going in one direction and the bottom half is going in another. He would have read this book at least a couple of years ago.

Maybe Crashland?

The cover doesn't match, but perhaps there's a different edition out there. Could it be Another Amy perhaps? The plot seems quite similar to what you describe.
