Macklin Celebrini and Will Smith thought they were getting a fresh start when they bought their first house together. They were not expecting the house to come with a ghost. She died there years ago, and for reasons she doesn’t understand, she’s never been able to leave. She’s spent a long time alone—until two very alive, very loud hockey players move in. At first, the haunting is accidental. A cabinet slams. A door opens. Something falls off a shelf. Then she realizes something important: Macklin Celebrini is absolutely terrified of ghosts. And, unfortunately for him, she’s bored. What starts as a few harmless scares slowly turns into something neither of them expected. Because the longer Mack and Will live in the house, the more she begins to wonder if maybe being stuck there isn’t quite as lonely as it used to be. And Mack? He’s starting to wonder if the ghost haunting his house might be his favorite roommate.
