When I left for college, I put 1,000 miles between my future and my past. I'd made a choice - I was going to cross back to the other side, to live with the living. I just didn't know how. And then I met Nate Preeter. An All-American baseball player, Nate wasn't supposed to notice a ghost-of-a-girl like me. But he did. He shouldn't want to know my name. But he did.
