The book is about Pluto, which was demoted to the status of dwarf planet in August 2006 by the International Astronomical Union, thereby depriving it of its planet-hood.The book also focuses on the fact that many Americans rallied their support for this icy dwarf on the edge of the Solar System because it was discovered by an American.
The book explains in full detail the journey of Pluto's life from its days as Planet X, to its discovery in the early 20th century and all the way to its current title as a Trans-Neptunian object.
