I do hold a certain fondness for epistolary novels, and over the course of the story, Cadence's letters and situation gain complexity, becoming what is a very tightly woven story about a young girl learning to rescue herself. She also writes several of her own versions of fairy tales, which are both funny and touching.
Letters from Rapunzel won the Ursula Nordstrom First Fiction Contest, and with the way the different facets of the story come together, I am not surprised. This was a very impressive book.
