The Serpents Shadow-Book3

So Far in The Serpents Shadow, Carter and Saide have still been working hard to find out a way to defeat Apophis. They want to use his Shadow to try and defeat him but they dont know enough about the Shadow Capturing magic. Meanwhile Walt is getting closer to dying from his Curse. They actually now need Walt because he has the Amulet magic that can help them. So basically its a "race" or Deadline to defeat Apophis before he takes over Earth.  They need to do this before Walt dies and Apophis gets stronger everyday. He has been attacking numerous places and he wants to get rid of things that can help Sadie And Carter such as the book Setne wrote. Now that all of those book are gone, they have lost a big clue. Setne has been dead for a long time now but they might actually see him again through the power of magic....
