Sunday Woodcutter is the seventh daughter of a seventh daughter. Not only does that come with an enormous family, but the things she writes in her journal also have a tendency to come true. When Sunday meets a frog in the Enchanted Wood who asks about her stories, the two develop a unique and precious friendship that quickly deepens into something quite magical.

One night, Sunday kisses her frog goodbye and leaves, not realizing that her love has transformed him back into Rumbold-rebellious crown prince of Arilland and a man Sunday's family despises. The prince returns to his castle and announces a royal ball, inviting every eligible young woman in the country. Rumbold hopes to make Sunday fall in love with him as the man he is and not the frog he was.

Sunday does feel a strange, strong attraction to this prince she barely knows. But what other twisted secrets might lie hidden in his past...and hers?
