Summary: The parallel book to Lost Hero
This is a book that is hard to discuss without at least some spoilers. The Percy Jackson Series was a complete series based around the character Percy Jackson, son of the Greek God Poseidon, as he discovers that he is a demigod and works to save the gods from being other thrown by the Titans.
This series is after the first series, but has some of the same characters. So I would read Percy Jackson first, then this. In the first book (spoilers start here) we are introduced to Jason Grace, son of Jupiter and his two friends Leo and Piper. What is revealed at the end of the first book is that the Greek Gods also have Roman sides to them and there is a whole world of Roman demigods that have been kept apart from the Greek demigods.
Jason was from the Roman side and was sent to Camp Half-Blood (the Greek side) by Hera in order to join the Greek and Roman demigods together to overthrow Gaia and the Giants.
