September has been crowned as Queen of Fairyland but the Kingdom is in chaos. The magic of a Dodo egg has brought every King, Queen, or Marquees of Fairyland back to life, each with a claim on the throne and their own plots and histories. In order to make sense of it all, and to save their friend from a job she doesn't want, A-Through-L and Saturday devise a Royal Race, a Monarchical Marathon, in which every would-be ruler will chase the Stoat of Arms across the nation, and the first to seize the poor beast will be crowned. Caught up in the madness are September's parents, who have crossed the universe to find their daughter.
