A magical castle with a life of its own, and a plucky princess who will defend it at all costs...Tuesday is Princess Celie's favourite day. Castle Glower magically grows a new room, a turret or sometimes an entire wing! No one quite knows how. When the king and queen disappear, a secret passageway appears. The Castle is definitely trying to tell her something. But it's down to Celie to find her parents, hold on to the kingdom and protect her home before it's too late.
