Emily and her family have just moved to a new house out in the country. Emily thinks it is going to be really boring with no close neighbors and nothing but trees in every direction. When she goes to explore the woods, Emily finds a locked and abandoned playhouse. Through the window, she sees that there is a mural of a forest inside and even a picture of that same playhouse. Who does the playhouse belong to? Soon Emily discovers that there is a mystery inside that playhouse and maybe even a ghost! Can she figure out the secret of the playhouse?
