When Luna and her sister Aurora move into a real-life tower, it seems like it could be a dream come true. Their Dad promises them a fairytale… but it things turn out to be quite the opposite! The tower’s falling apart, Dad’s still job-hunting, and the top room is off-limits.

Aurora struggles at their new school and begins spending all her time with her imaginary friend, Tansy. A person who she seems to believe is real. When strange and unexplained things start happening around the girls, Luna begins to wonder… is the tower really cursed? And is this ‘Tansy’ not so make-believe after all…?
