So far what i have read of them, I don't think he is because it is Egyptology, Not Greek mythology.
After Percy Jackson and the Olympians, and the Heroes of Olympus there is The Kane Chronicles.
the Percy Jackson books
It is an Egyptian version of the Percy Jackson series.
It's a matter of opinion.
Yes, Rick Riordan is currently writing two main series: the "Percy Jackson" series and the "Magnus Chase and the Gods of Asgard" series. He also has various other spin-offs, short stories, and companion books related to his mythological worlds.
Well if you like Percy Jackson you will like the Kane Chronicles. They are by the same author and they are really good. Sarcasm + Magic = AWESOME!
The second book in the series is the throne of fire
Actually he has Percy Jackson series and the Kane chronicles. The lost hero which is out now is a sort of sequel to the Percy jalson series. No one can get enough of Percy!
Well, they already have the 5. There are no more. But if we are lucky, Rick Riordan might come out with a second series of Percy Jackson. He right now has the Kane Chronicles.
No, The Red Pyramid is a book from the series called The Kane Chronicles. Even though Rick Riordan is the author of both of them, the Percy Jackson books are part of the Percy Jackson and the Olympians series. Percy later became a supporting character in the Heroes of Olympus series.
I'm sorry to say there are only going to be 5 Percy Jackson books. But there will be a sequel series coming out soon called the gods of Olympus and the Kane chronicle's.
When I read the book I read that they are probably going to have a "relationship" if u know what i mean They start to date and in the new series Percy goes missing and Annabeth goes out looking for him
