I'm guessing you mean the films rather than the books. They've started filming the sequel, and it's due out in 2012.
Apparently 20th century fox are making the second Percy Jackson film, they are saying that they might start filming in the summer of 2011 so that the film can be released in 2012.
He is making another Percy Jackson series. The next book is called The Lost Hero. It comes out in October.

Percy Jackson and the Olympians started in 2005 after the lightning thief was published.

I found Percy Jackson a great book

They started going out in the Demigod Files, specially the story Percy Jackson and the Bronze Dragon.
It depends on when you start to watch it its 2 hours though
After the 5th and final Percy Jackson book is finished, Rick Riordan is going to start 2 new series . The Red Pyramid And the Heroes Of Olympus
NO! Read the book. They don't even start flirting till, like, the second or third book. And the movie has almost nothing to do with the book.
Percy Jackson first kisses Annabeth in the fouth book, Percy Jackson and the Labyrinth, during their escape from a bunch of Telkhines. In the end of the fifth book, Percy Jackson and the Last Olympian, Percy and Annabeth kissed in the hill, after their celebration dinner. Then, the campers, whom all was eavesdropping, lifted them on their soldiers and dumped them into the lake, where Percy then creates an air bubble and had a "underwater kiss of all time".
