Luna Andersen is reticent to return to her small town of Alton, Minnesota, but she has no choice because the woman who raised her is dying of cancer. Seeing her actual mother alive and well, on the other hand, is one of the reasons she stayed away for so long. When Luna glimpses a photo of a man closely resembling her dead twin sister, she wonders if he could be the father she never knew. And if he is, it throws a wrench in pursuing a romantic relationship with the one person she ever considered loving-her childhood friend Brad. Just as she inches closer to uncovering the mystery, Luna gets scared and does the thing she's always done when things get hard. She packs her bags. Again. Ruining her chances with Brad. But this time Alton has other plans for her.
