The Olympian Gods have made it to the 21st century AD. We may not have heard much about them in the last two thousand years, but they're still controlling what we humans are up to - or at least they think they are.
The reality is that the Gods are like us - they've got problems!
Zeus is still Top God on Mount Olympus, but he's got issues with many of the younger gods. His brothers, Hades and Poseidon, have issues with themselves - they're getting too set in their ways ruling the Underworld and the Seas; they probably need a job change.
But help is at hand from an unexpected source - we humans.
It's surprising what a dose of good common sense can do for even the most powerful of the gods, especially when it comes from a couple of teenagers!
