This is the best series EVER!!!!  It's about a boy who finds out that he's a demigod (one parent is mortal, the other is a Greek God) and has to go on a certain mission in order to not get killed.  It takes place now and it is a really awesome series.  I recomend it to everyone.  I don't want to give too much away, but he meets many figures in Greek Mythology in today's world.
