Ghosts, Magic, and a Deadly Serpent God! Spooky spells and murderous magicians bring this supernatural series to its breathtaking conclusion! No matter what they do or how hard they try, Carter and Sadie Kane can't seem to defeat the ancient Egyptian chaos snake. Now he's back and threatening to plunge the world into eternal darkness. With the magicians on the brink of civil war and the gods themselves divided, Carter and Sadie must stand alone. Their only hope is an ancient spell that might turn the serpent's own shadow into a weapon, but that magic has been lost for a thousand years. To find it again, the Kanes must rely on the murderous ghost of a powerful magician who might lead them to the serpent's shadow...or to their deaths in the underworld. The fate of the world is at stake when the Kane family fulfills its destiny in the heart-racing finale to the Kane Chronicles.
