This is the first book in The Heroes of Olympus series, which is the second series of the Percy Jackson and the Olympians series.
This new series picks up after the events in the first one which was centered around Percy Jackson. Percy Jackson was a huge hit around the world and this new series promises to continue the sensation.
In this book, the main protagonist is Jason. He wakes up and finds that he doesn't remember anything, not even who he is. But to his two best friends Leo Valdez and Piper McLean, he has been around for months. Jason, however, is sure that he has never seen the two before.
While they are on a school trip, they are attacked. During the attack they meet two demigods, one of whom is Annabeth. Soon, they learn that they themselves are demigods, the children of the Gods and mortal parents. They also learn that Annabeth is searching for someone who has been missing for three days- Percy Jackson.
They are escorted to Camp Half-Blood where they hope things will clear up. But things just get worse. Problems are arising, Olympus has sealed itself off and Jason still can't remember a thing. Not to mention Piper has worries of her own, worries that shes afraid to tell anyone of. The three of them must set out on a quest to find out what is wrong and hopefully bring things back to normal.
I have to say that I liked Percy Jackson a lot, and this is perfect continuation to that series. Things are pretty much the same as before. The only thing that has changed is the characters. Even that isn't too different. All the old characters are there, minus Percy. But they don't really play too important roles; after all, this is a new series and the old characters need to move aside for new, fresher ones.
The pace is fast, and the story is entertaining. I like the new twist of the Roman Gods. It lends the new series a different touch from the older one. The Greek ones are still there, but the Roman ones heighten the interest in the new series even more.
Anyone who read and loved Percy Jackson will definitely want to read this book.
