If you're wondering whether you should start reading the Rick Riordan Percy Jackson books in order - and what is the right order of the series anyway - on this page I'll let you know, along with a brief review of each of the main books.
I will also give the right reading order of the new series, Heroes of Olympus, where Percy Jackson is still present, but is no longer the main hero of the day. Granted, I am not so enthralled by this new series, but I know lots of people who are.
The original Percy Jackson And The Olympians series focuses on a young guy of age 12, Percy Jackson, who is in sent from one boarding school to another and is just about to get kicked out of there as well. He doesn't fit in really anywhere, and he's always totally out of place.
No wonder, since he's the son of one of the Greek goods, mind you, which makes him kind of a demi-god himself.
So let's see what kinds of troubles this pre-teenage kid goes through and what adventures expect him on the road.
