The Throne of Fire (2011) is the second book of The Kane Chronicles series by Rick Riordan. It continues from the events of the last book. The book is based on events from Egyptian mythology.

The chaos snake Apophis is breaking free from his prison, and Carter and Sadie Kane must stop him before he escapes and plunges the world into darkness and chaos. Carter and Sadie are now training magicians to join the House of Life.

Carter and Sadie decide that they will look for the three parts of the Book of Ra in order to awaken the sun god Ra. They also must stop Apophis from escaping. Along the way, Carter and Sadie encounter many obstacles.

Their grandparents are being hosted by the vulture goddess and baboon god, causing them to viciously chase after Sadie and her friends. Carter is trying to free Zia, a girl who was hosted by the river goddess Nephthys. In the meantime, Sadie and her trainee Walt have gotten one of the scrolls to the Book of Ra, but they must try to escape from some really angry mummies led by a Roman ghost.

After awakening Ra, Carter, Sadie, and the dwarf god Bes bargain with the moon god Khonsu to add more hours to the night. They play three rounds of senet, an Egyptian board game. If they win, they will win extra time, which they need in order to continue with their quest to stop Apophis. Unfortunately, if they lose a round, one of their identities will be consumed by Khonsu, causing them to lose all memories.

I thought this book was even better than the first book, The Red Pyramid. It was full of action, with combat and magic. The narrators described their quests in detail and also added humor and their own personalities into the telling of the story. The book is told from the views of Carter and Sadie, alternating narrators every few chapters. Most of the events are based on real events and deities from Egyptian mythology. I would rate this book 4.5 out of 5 stars, just because the book was somewhat slow at parts.

The Throne of Fire is approved for students from grades 6-8.
