      Rick Riordan does what only he can...create a mystical tale that pulls you in and makes you hang on for dear life.  The Kane Chronicles (Book 1, Red Pyramid and Book 2, The Throne of Fire, Book 3 Serpent's Shadow) are excellent examples of that!  Riordan weaves Ancient Egypt with modern day in a very real way.  Two siblings, Carter and Sadie are separated by an ocean.  Carter lives with his dad, traveling as a archaeologist.  Sadie lives with her mom's parents in London.  On their traditional get together, their lives change drastically.  Carter's father is not really what he seems.  Not only that, but he helps very powerful Egyptian gods loose.  Carter and Sadie now have to save their dad and figure out how to help out.  Get on board this wild ride and hold on! 
*Mrs. B's note:  It will help greatly if you research Egyptian gods as you read this book.  It will make so much more sense. 

     In book 2, Throne of Fire, Sadie and Carter are back at fighting ancient monsters.  Without giving too much away, Sadie and Carter are now running the House of Life in New York.  Their uncle is away and put them in charge of training the new recruits.  Sadie gets separated from Carter when she goes to celebrate her birthday in London.  Instead of finding Grandma and Grandpa, she finds a vulture and a gorilla- well not really but close enough!  Carter has his own problems back in New York with his new "pet".  This time their adventure leads them all over ancient Egypt.  Their challenge is even bigger this time and they don't have Horus and Isis to help them.  Read more to see if they make it back to New York alive! 
*Mrs. B's note: Keep researching about Ancient Egypt.,  especially the timeline of the Egyptian Empire. 

    In book 3, Serpent's Shadow, Sadie and Carter are trying to save the world- yet, again!  The siblings are trying to stop Apophis from swallowing Ra (sun god) and destroying the whole world.  It doesn't help matters any that they are losing every scirmish that arises with the Serpent of Chaos.  They were responsible for the destruction of the 51st Nome in Dallas.  Sadie is worried about Walt and his curse of a shortened life.  Carter is trying to be a leader, but is suffering from self-doubt.  Throw in the mix a deranged ghost from ancient Egypt and you have quite a head-ache.  This was an excellent final book for the Kane Chronicles.
