Thursdays with the Crown

Castle Glower's towers have transported Princess Celie, her siblings and her pet griffin, Rufus, to an unknown land—a world of wild griffins, shadowy forests and castle ruins. 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! Why has the castle sent Celie and her siblings here, and will they ever get back home?
