When Perce, Andy, Eddie and Well'ard go on a school trip to London, they don't expect to find Orpheus busking on the Tube. And their plans for the day don't include joining the most famous musician in Ancient Greece on a roller-coaster ride through the darkest reaches of the underworld. But we all know what they say about the best-laid plans...Another madcap myth adventure in which our heroes meet a hick from the Styx, a postman's worst nightmare and three Fates worse than death. When Orpheus's lyre fails him, can karaoke save the day? Once again the fearsome foursome are up to their necks in a hilarious re-invention of Greek myth from the two Steves.
