Elio and Luna just wanted to survive a vacation in Greece among old stones with their archaeologist parents. Instead, they find two amulets, end up on Mount Olympus, and the gods saddle them with a far-from-easy mission: hunting mythological monsters around the world. Their first stop is Prague, where a hungry minotaur is wreaking havoc in a mirror maze. 

Armed with a bow and a lyre, these twins are about to get themselves into a truly epic mess. Two very brave twins, an Olympus full of clueless gods, and a hungry minotaur lost in a mirror maze. 

The adventure will be epic... if Elio and Luna manage to save the world!
