Description: Trouble-prone Percy Jackson is having problems in high school - but that's the least of his challenges. It's the 21st century, but the gods of Mount Olympus seem to have walked out of the pages of Percy's Greek mythology texts and into his life. Percy has learned that his real father is Poseidon, god of the sea, which means Percy is a demigod - half human, half god. At the same time, the powerful gods on Olympus are feuding, which could launch a war enveloping our entire planet. (20th Century Fox)
