Cut and Run

 Fiction by Mary Burton

Twin sisters, separated at birth, are at the center of this story. Medical examiner Faith McIntyre knows she was adopted, but her (now dead) parents had never wanted to discuss it, like a shameful secret. Macy Crow, on the other hand, didn't consider her origins a secret; as she was a pale blonde child with two dark-skinned parents, her own adoption had always been obvious. When these two women find each other and realize that they look identical, secrets will finally be revealed.

This was a good-enough story, but I think I would have liked it better in print than on audiobook.
