Although, Rick Riordan's style of writing is different then J. K. Rowling (author of the Harry Potter series), both of these authors created two very creative and exciting world and they both keep readers wanting for more!
Rick Riordan actually used myths, fantasy and realistic fiction to make such a nice story filled with adventure and excitement. I think Rick Riordan planned out the whole story very deeply because the author made everything connected including Jason Grace, the brave demigod's (half mortal, half god) appearance in camp Half- Blood who's memory is taken by Hera, the goddess of family, and Percy Jackson's, the hero from Rick Riordan's previous series about Olympus, disappearance.
The story started with Jason, Piper and Leo (Jason's two best friends) going to this school trip but Jason doesn't remember anything on the way. Their trip was at the Grand Canyon where, when they went they were attacked by storm spirits, or venti who tries to kill them but Jason' s coach Gleeson Hedge (who is actually a satyr but Jason doesn't know) saves them by sacrificing himself for the three demigod.
Later, Jason, Piper and Leo were taken to camp Half- Blood by Annabeth where they had to go in a quest to get Jason's memory back, stop the evil giants from rising and save Piper's dad. What really amazed me is that Riordan used the same prophecy from the end of the last Percy Jackson series book for the The Lost Hero and will use the prophecy for the whole Heros Of Olympus series.
The last part was amazing when Jason completed his quest and stopped Gaea, Mother Earth who is the enemy, from rising entirely and figured out the truth of Percy Jackson's disappearance. Hera, the goddess, made an exchange. There is another camp for demigods who follow the Roman gods and the roman rules rather than the Greek rules which camp Half- Blood follows and there is where Percy is. Jason is actually from the Roman camp because he is more familiar with the roman aspects. Hera switched the two campers because the two camps has always fought and Hera wanted both camps to learn that both camps aren't very different from each other. Making everything connected was a really nice touch for the end of the story because it got me very jumpy for the next book.
