Jason has a problem. He doesn't remember anything before waking up on a school bus holding hands with a girl. Apparently she's his girlfriend Piper, his best friend is a kid named Leo, and they're all students in the Wilderness School, a boarding school for "bad kids." What he did to end up here, Jason has no idea—except that everything seems very wrong.

Twelve-year-old Percy Jackson is about to be kicked out of boarding school...again. No matter how hard he tries, he can't seem to stay out of trouble. But can he really be expected to stand by and watch while a bully picks on his scrawny best friend? Or not defend himself against his pre-algebra teacher when she turns into a monster and tries to kill him? Of course, no one believes Percy about the monster incident; he's not even sure he believes himself.

At least, that's been the case so far . . . Now Nico is being plagued by a voice calling out to him from Tartarus, the lowest part of the Underworld.

De gale guder, mytologiske monstre og seje helte er tilbage i Rick Riordans nye serie Olympens helte. Percy er forvirret. Han kan knap nok huske sit eget navn, og selv efter at ulven Lupa har fortalt ham, at han er en halvgud og trænet ham til kamp med en besynderlig fyldepen, er der stadig meget, som ikke giver mening. På en eller anden måde lykkes det ham at finde vej til en lejr for halvguder, men lejren føles ikke rigtig.
