Magical Misperception

For one magical summer, Jona is selected to be a companion to Prince Lee and help him practice social graces. Despite her joy, however, she is expected to follow the rules: never speak to the queen unless spoken to, never forget she's merely a servant, and never, ever fall in love with the prince.

Are the differences between a prince and a commoner too large to overcome, or are they just a matter of magical misperception?
