The Sigh — Marjane Satrapi

From the author of Persepolis, comes this illustrated fairy tale. Rose is one of three daughters of a rich merchant who always brings gifts for his girls from the market. One day Rose asks for the seed of a blue bean, but he fails to find one for her. She lets out a sigh in resignation, and her sigh attracts the Sigh, a mysterious being that brings the seed she desired to the merchant. But every debt has to be paid, and every gift has a price, and the Sigh returns a year later to take the merchant's daughter to a secret and distant palace.
