When sixteen-year-old Tiffany Winters strolls past Willowtree Care Home for the Elderly, she notices that something isn't right. There is just a certain 'feel' to the place. After she quizzes her Mum, she discovers that her great-grandfather lived and died there, and she wants to know more about him and the Home-- but things are never that simple. Willowtree has been taken over by a new management team that nobody ever knows anything about, there are no records or memories of her late grandfather, and-- as if that wasn't enough-- there is a mysterious boy on the loose. Together, Tiffany and her new best friend, Betty, must piece together what they know to 'build the full puzzle', and only then will they be able to solve the mystery behind the Care Home and her great-grandfather. But the only way to do so? Wander into a secret warehouse that leads into another world full of ghosts, secrets, and rows upon rows of suitcases...
