Carter and Sadie Cane, descendants of the Magical House of Life, are in pretty big trouble.

Despite their bravest efforts, Apophis, the giant snake of Chaos, is still threatening to plunge the world into eternal darkness. Now the Kanes must do something no magician has ever managed: defeat Apophis himself. No pressure there then.

Battling against the forces of Chaos, their only hope is an ancient spell - but the magic has been lost for millennia. Will they find the serpen't shadow, or will they be led to their deaths in the depths of the Underworld?

Don't miss any of the explosive action in the final thrilling instalment the The Kane Chronicles trilogy.
