Mal Caldera is dead. Not that she cares. She only feels bad that her younger sister, Cris, has been left alone with their religious zealot of a mother, trying to pick up the pieces. While her fellow ghosts party their afterlives away, Mal is determined to make contact with Cris from beyond the grave. She enlists the help of reluctant local medium Ren, and together, they concoct a plan to pass on a message to Cris. But the more time they spend together, the more both begin to wonder what might have been if they'd met before Mal died. Mal knows it's wrong to hold on so tightly to her old life. Bad things happen to ghosts who try to interfere with the living, and Mal can't help but wonder if she's hurting the people she loves by haunting their lives. But Mal has always been selfish, and letting go might just be the hardest thing she's ever had to do...
