Hercules Braver, modern-day son of Zeus, is about to face his BIGGEST challenge yet... A legendary Greek monster has escaped from the underworld!

Hercules is ready to start a new school year as the BEST demigod when, to his surprise, his cousin Theseus suddenly comes to stay from Greece. Theseus, son of Poseidon, is a young demigod just like Hercules. But right as Herc was (finally) preparing to be a heroically good role model, infuriating Theseus causes TROUBLE at every turn!

But soon the boys are forced to work together - because Zeus has been so focused on writing a book that he's lost control of the cosmos... and now the universe is in jeopardy. One of the most terrifying monsters in Greek myth has hatched an escape from the underworld! With their dads pre-occupied, it's up to Herc and Theo to track down and stop the Minotaur.

No doubt about it, this is Herc's most high-stakes adventure yet. Will the boys become monster-slaying heroes like their namesakes? Or will they learn that myths might not have the full story?
