In this final book of the Kane Chronicles trilogy, Sadie and Carter are facing off against the evil Serpent Apophis. They have gathered many allies around them, but their enemies are more powerful than ever. There is only one way to stop Apophis from rising and devouring the sun; they must discover an ancient spell hidden by a magician who died centuries ago. Fortunately, their father has power in the Duat to locate the magician's ghost. Unfortunately, the ghost is insanely murderous and sure to betray them. It's just another day for the Kane siblings, fighting off monsters and doing the impossible.

I loved this fun adventure! Sadie is full of spunk and sass, and Carter is serious and responsible. They make a great team, and I love the sibling dynamic between them. In this book, they can almost read each other's thoughts at times. They are in tune with one another, despite their differences, because all their adventures together have forged a strong family bond.

I enjoyed the adventurous plot and learning all about Ancient Egyptian legends of the gods. The setting in this book mostly focuses on Egypt where all the battles take place. But the gods have the power to reveal themselves in many places and in many forms.

I enjoyed the writing style which jumps back and forth between narrators. Sadie and Carter take turns telling the story from their point of view. Normally that would be annoying to me, but it's very well organized with Sadie narrating one chapter and then Carter narrating the next one. Since it is so well delineated, and since they both have very unique voices, it works great for this story.
