Kane chronicles (Graphic novels)

After their father's research experiment at the British Museum unleashes the Egyptian god Set, Carter and Sadie Kane embark on a dangerous journey across the globe, a quest which brings them ever closer to the truth about their family, and their links to a secret order that has existed since the time of the pharaohs.

Despite their best efforts, Carter and Sade Kane can't seem to keep Apophis, the chaos snake, down. Their only hope: find an ancient spell that might turn the serpent's own shadow into a weapon. The conclusion to the Kane chronicles trilogy.
