At this point I am not seeing anything indicating a sequel to this movie. I searched around under the movie title, the actor and even the main character name Percy Jackson and nothing seems to be showing up. I would definitely keep an eye on sites like IMDB to see if they update.
Since the movie says it was released in 2010, it's possible a announcement about a second may not come until later this year or even in 2011. Hope this helps!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
