Rick Riordan is working on the third book but it's probably going to be 5 books long like Percy Jackson
No its not, its a trilogy so its only 3 books you can check his website if you don't believe
I think there are going to be at least three books in the series. Because the other books that Rick Riordan did were the Percy Jackson books. There were five books in the Percy Jackson books so I think that there are going to be at least three books in the Red Pyramid series.
