"Jack is an ordinary boy except that his father happens to be Death. Nadine is a perfectly normal girl except that her Mother is--oh well, that's a Secret ... together, these two incredibly average children discover the lemon-headed villain behind the destruction of the Magical Creature Reserve and piece together his plot to divide the Golden and Black Bloods. They may even save a few lives"--Back cover.
