I'm pretty excited about Rick Riordan's new series, which focuses on the Egyptians and starts with his recently released The Red Pyramid
This is aimed at mid-grade readers, and is about as consistent as the Percy Jackson stories. (Starts out very exciting, gets a little slow in the middle, finishes with a bang.) I definitely recommend it if you enjoyed the previous series. This one is nice because the narrative goes back and forth between the two siblings, so you get some of Sadie's perspective and some of Carter's.
If there are other stories that are adaptations of Egyptians mythology and tales, I'm not familiar with them, although according to The Red Pyramid, "The Sorcerer's Apprentice" is based on an Egyptian story. Does anyone know any other modernizations or adaptations of Egyptian stories?
