This book details the Egyptian gods that are featured in the Kane Chronicles trilogy, and some of back story for the characters. It includes some real Egyptian history, and information about Egyptian artifacts found museums around the world. There are sections about the spells that the Kanes use in the books and the weapons and artifacts they use to create magic.

This book did not have any information that was not already included in the main trilogy. I did not care for the artwork. Waste of time to read this.
Even the real Egyptian history was just basic things about mummification and pyramids that any schoolchild would already know.
It's a shame that this book is so boring, because I really love the Kane Chronicles trilogy.
