Ever since the gods of Ancient Egypt were unleashed in the modern world, Carter Kane and his sister Sadie have been in trouble. As descendants of the House of Life, the Kanes have some powers at their command, but the devious gods haven't given them much time to master their skills at Brooklyn House, which has become a training ground for young magicians. And now their most threatening enemy yet -- the chaos snake Apophis -- is rising. If they don't prevent him from breaking free in a few days' time, the world will come to an end. In other words, it's a typical week for the Kane family. To have any chance of battling the Forces of Chaos, the Kanes must revive the sun god Ra. But that would be a feat more powerful than any magician has ever accomplished. First they have to search the world for the three sections of the Book of Ra, then they have to learn how to chant its spells. Oh, and did we mention that no one knows where Ra is exactly?
