The Red Pyramid was a great book about two siblings, Sadie and Carter Kane, who discover that they are descendants of two great Egyptian pharaoh blood lines. At the same time they discovers this shocking news, their father is captured by the evil god Set. The Kanes have to save their father and rescue the world!
The Percy Jackson and the Olympians series also by Rick Riordan.
I would recommend this book to any kid that liked Riordan's previous series, Percy Jackson and the Olympians, or is interested in Egyptian mythology.
