Percy's quest teaches that, in order to overcome obstacles, you need help, support, and guidance from friends, mentors, and people who know more than you. Percy must persevere despite his self doubt in order to protect his friends and his home. Tyson is a cyclops but not bloodthirsty like other cyclops; he makes it clear that you shouldn't judge someone before you get to know them.
Positive Role Models & Representations
Lots of fantasy action. A flashback shows a young girl being killed by a cyclops and then turned into the roots of a magical tree. A giant Colchis Bull wreaks havoc on Camp Half Blood, where it injures several kids before fighting directly with both Percy and Tyson. There are three big fight scenes between Percy and his friends and the bad guys. Polyphemus, a huge cyclops, keeps threatening to eat either satyrs or half bloods and fights with Percy, Annabeth, Grover, and Tyson. When brought back to life, Kronos is a frightening sight. Two characters are presumed dead -- and one does temporarily die before the golden fleece revives her.
Some discussion of how the gods have children with humans and other creatures. Percy and Annabeth share some lingering looks and are protective of each other but aren't outright romantic.
A couple of "damn"s. A character almost says "bitch," but it comes out with a long "bbbbb" sound.
Some of the characters wear Converse All-Stars. A UPS Store is shown during a pivotal scene, but it's actually an "OPS" (Olympian Parcel Service).
