In this thrilling conclusion to the Kane Chronicles, Carter and Sadie are down to their last chance to destroy the chaos snake Apophis. If they can't get rid of him once and for all, he will plunge the world into eternal darkness. The Kanes don't have much help, though, as the magicians of the House of Life are wasting time fighting with each other and the gods are divided by their own squabbles. It's up to Carter, Sadie, and the other young magicians of Brooklyn House to battle Apophis and his forces. Their only hope is an ancient spell that would turn the snake's own shadow into a weapon against him. Problem is, the spell has been lost for centuries...and time is running out.
This was my favorite book in the Kane Chronicles. I had trouble following the others, perhaps due to my lack of knowledge of Egyptian mythology, but I guess I'd learned enough from the previous books to help this story make sense. The action is pretty much nonstop, so I couldn't put the book down. Carter and Sadie both seem to grow up a little, which is good to see as the series concludes. I like the way everything came together for a very satisfying ending. Well done!
