Princess Celeste is bored to tears, and her brothers, Prince Jude and Prince Torrin, aren't doing much better.

In a palace where all they have to look forward to are endless games of croquet and barley-water soup for supper, they don't have much by way of excitement. Until the one night Torrin sees a light in a forgotten tower of the palace, and they meet a wonderful and mysterious aunt who unlocks a brand-new world of adventure they will never forget.
