Edward is the King of England. He's also dying, which is inconvenient, as he's only sixteen and he'd rather be planning his first kiss than who will inherit his crown. Jane, Edward's cousin, is far more interested in books than romance. Unfortunately, Edward has arranged to marry her off to Gifford to secure the line of succession. And Gifford is, well, a horse. That is, he an Eðian (eth-y-un, for the uninitiated) who becomes a chestnut steed every morning, but wakes as a man at dusk, with a mouthful of hay. Very undignified. The plot thickens as the three are drawn into a dangerous conspiracy, and have to engage in some conspiring of their own. But can they pull off their plan before it's off with their heads?
