September never expected to be crowned Queen of Fairyland—especially not by accident. But when rivals emerge claiming their own right to the throne, a Royal Race is declared: whoever reaches the finish line first will rule Fairyland.

Joined by her loyal friends—the Wyverary, A-Through-L; the boy Saturday; the changelings Hawthorn and Tamburlaine; the wombat Blunderbuss; and the gramophone Scratch—September embarks on a journey filled with enchantment and peril.

Meanwhile, her parents have crossed the universe to find their daughter.

Who will win the race? What fate awaits September, Saturday, and A-Through-L? The answers are more surprising and magical than you can imagine.
