Rani lives in a luxurious palace full of busy adults, but she's lonely. Being the only princess in the kingdom is boring, tedious, dull. She has no one to play with - except her baby brother, who doesn't count! So one morning, Rani decides to leave for the beach in search of adventure. She's sure it will be the opposite of her life in the palace: wonderful, marvelous, fun! But in the world outside the palace walls, Rani isn't a princess anymore, she's just a kid who's not so great at building sandcastles. And what she finds there is something she didn't even know she was looking for: a friend.
