Why can't Percy Jackson's adventures continue?
For those who do not know what I am talking about, Percy Jackson is a young teen who discovers he is the son of Poseidon, Greek god of the sea and earthquakes. He learns that the legendary beings of Greek mythology still exist including Greek Gods, Titans, monsters, etc. Mt. Olympus has moved to the 600 hundredth floor of the Empire State Building in Manhattan. After he finds out who he is, he goes on many adventures with his demi-god friends.
Within the book series, there was a great prophecy (a revelation of a future event) that a child of the Big Three (Zeus, Poseidon, Hades) will either destroy or save Olympus. Percy saves Olympus and the prophecy came true. There is another great prophecy and it has not been answered. So what is up with that? This was supposed to be the final book in the series. It can't end now...now since there is another great prophecy.
There needs to be another book!
