Other Riordan mythology series (standalone from Percy Jackson): The Kane Chronicles (Egyptian mythology, 3 books), Magnus Chase and the Gods of Asgard (Norse mythology, 3 books), The Chalice of the Gods (Percy Jackson returns, 2023 — new standalone). These can be read at any point after the original Percy Jackson series.
Do You Have to Read Them in Order?
The original 5 Percy Jackson books must be read in order — they form one continuous story. The sequel series (Heroes of Olympus, Trials of Apollo) should also be read in order after the original. The Kane Chronicles and Magnus Chase are more standalone and can be read after finishing the original Percy Jackson series, in any order.
