Ava Kirkland knows three things for certain: One, Bradley will always be her BFF. Two, science is the best subject ever. Three, ghosts don't exist. Two out of three ain't bad. Twenty years ago, Mosley Manor was left abandoned. The haunted house of White's Chapel, Tennessee, has become the local dare-the place kids sneak to see if they are brave enough to go inside. Ava isn't scared of Mosley Manor in the slightest. She believes in facts. According to her, anyone who is scared of Mosley Manor should be ashamed. Unless that person is her best friend, Bradley. He gets a free pass because he's, well, he's been terrified of the house as long as Ava has known him. In fact, he was originally the person who told her about the house and all the ghosts inside. Unfortunately for Ava, her parents decide to buy their first house (YAY!), and it ends up being Mosley Manor (no...). Ava isn't afraid of the place, just not happy about leaving her old rental house next to her BFF. It's also not wonderful that it's the only thing anyone at school wants to talk about. Ava's brother starts acting even weirder than normal, Mama and Daddy never used to fight like this, and by golly, those upstairs doors have minds of their own. Ava may not believe in ghosts, but they certainly believe in her.
