When the skies clear after a storm, Zee starts seeing ghosts. When she tells her classmates, only her best friend Elijah believes her. Worse, mean girl Nellie gives Zee a cruel nickname: Ghost Girl. But whatever the storm washed up isn't going away, as everyone around Zee begins to behave strangely. To put things right, Zee must embrace the differences that make her Ghost Girl. And all three of them--Zee, Elijah, and Nellie--will have to work together if they want to give their ghost story a happy ending.
