The Hortlak by Kelly Link (Part 1 of 2)

Summary: "Eric was night, and Batu was day. The girl, Charley, was the moon. Every night, she drove past the All-Night in her long, noisy, green Chevy, a dog hanging out the passenger window. It wasn’t ever the same dog, although they all had the same blissful expression. They were doomed, but they didn’t know it." *
