Tuesdays at the Castle (Tuesdays at the Castle Series #1)

Tuesdays at Castle Glower are Princess Celia's favorite days. That's because on Tuesdays the castle adds a new room, a turret, or sometimes even an entire wing to itself. No one ever knows what the castle will do next, and no one - other than Celia, that is - takes time to map out the new additions. But when King and Queen Glower are ambushed and reportedly killed, it's up to Celia with her secret knowledge of the Castle's many twists and turns, to protect their home and save their kingdom.
