Miranda Jasper just wants her life to go back to normal. For Miranda, "normal" means living in a spooky old house in tiny Wilder, Kentucky, with her mom and granny who, like her, share a mysterious power called The Sight. It also means hanging out with her two best friends, Adam, a city kid who's had to adjust to small-town life, and Abigail, the ghost who haunts Miranda's room. But things are changing.

Miranda's mom has a new boyfriend, which changes things at home, and Adam announces he'll be moving away at the end of the school year. Worst of all, Miranda is rapidly approaching the age where she'll be too old to communicate with ghosts, which means she'll lose Abigail forever.

When Caylie, a classmate whose mother has been jailed under false charges, approaches Miranda and Adam, they know it's probably the last time the three of them—girl, guy, and ghost—will perform an investigation together. This adventure takes Miranda, Adam, and Abigail into dangerous territory as they try to save Caylie's mom and as Miranda must decide how much she's willing to risk for the chance to keep her ghostly companion.
