Every good fairytale begins with "Once Upon a Time," or they're supposed to at least. But for twenty-five year old Josephine Hart, her "Once Upon a Time" began with her literally crash landing inside a book of fairy tales and nearly crushing a frog—who is actually a prince. An annoying, snarky frog prince named Aneurin, seeking the kiss of true love to break his curse. He vows that if Jo agrees to help him find his princess, he will get her home.

With every turn of the page, their adventure leads them deeper into fairytales familiar to Jo. Through their journey, they discover that despite their initial clashing, they're both exactly what each other needs. It is only when they encounter a devious man with a talent for spinning straw into gold that they realize just how quickly their plot can take an unexpected twist.
