Haunting Zoe — Sherry D. Ficklin

Logan woke up with a big problem. He's extremely dead. No one from his former life seems able to see or hear him, making his afterlife little more than a miserable nightmare. That is, until the day of his funeral, when the bitterly sarcastic Zoe, a friend from his childhood, starts calling him out at his own wake. Now his only chance at moving on means dealing with his sordid past -- and the girl he never really got over.
