Tuesdays at Castle Glower are Princess Celie's favorite days. That's because on Tuesdays the castle adds a new room, a turret, or sometimes even an entire wing. No one ever knows what the castle will do next, and no one--other than Celie, that is--takes the time to map out the new additions.

"Castle Glower's towers have transported Princess Celie, her siblings, and her pet griffin, Rufus, to an unknown land. As they set out on a dangerous adventure to discover their whereabouts, they find an entire lost people, divided by the wishes of two wizards in a centuries-old quarrel over their beloved home--Castle Glower"-- Provided by publisher.

"After traveling to the seaside kingdom of Lilah's betrothed prince, Lulath, Celie and her companions are busy training griffins, enjoying wedding festivities, and finishing construction of a grand ship built from parts of the Castle. But on their maiden voyage, the Ship steers them far off course into uncharted waters"-- Provided by publisher.
