The Serpent's Shadow by Rick Riordan

This book did a great job of wrapping up the Kane Chronicles. I enjoyed watching the Kanes negotiate maintaining their own personality and individuality in the face of incredibly powerful gods whose help they needed to defeat the forces of Chaos. This trilogy is entertaining and similar in conception and execution to the Percy Jackson books (with a different set of gods, of course). It's a fun introduction to Egyptian mythology, and a compelling story.
