A Story About a Female Ghost and a Zombie

The story of a female ghost and a zombie, getting up to mischief and making their way through the apocalypse together. The heroine falls from a building, her soul leaves her body, and she sees a zombie biting her corpse. Then she becomes a zombie too. To stop “herself” from running around causing trouble and biting people, she has to follow her body everywhere and keep it in check. So the main plot is about keeping her own body under control while falling in love with a male zombie... And maybe climbing to the top of the zombie world along the way.
