"Erin loves her new home in the country. She has a big bedroom that overlooks a beautiful garden, and there's even a treehouse in the backyard. Everything is perfect . . . except for the ghost. At first, the ghost is nothing more than a nuisance, pulling Erin's hair, coloring on the walls, and getting Erin into heaps of trouble with her parents. But things become even stranger when Erin starts losing her memory. Sometimes it's only for a few minutes, and other times it's for a few days. It's almost as if she's fallen asleep! Erin is convinced the ghost has been taking over her body, but why? It's up to Erin to figure out how to quell the ghost before it can get her into even more trouble--or worse!".
