Zel is a retelling of the story of Rapunzel, told from the perspective of the girl, her suitor, and her mother, attempting to explain the motivations behind all three characters.
From the synopsis, this looked like a really good book. I guess I expected it to be a retelling with modern psychological insights. It didn't really live up to this. Instead, the story drifted a bit into magic and fantasy, and dodged the more human qualities of jealousy and insecurity that Napoli begins the story with. Like Sirena, this isn't really a children's book at all. It probably belongs with the Fantasy category instead.
