When two brothers went exploring, they soon stumbled across more adventure that they had hoped for. The Odyssey was a tiny planet hidden within the surface of the Earth – trapped and fixed in the age of Ancient Greece, where mythical beasts, Gods and Goddesses, Kings and Queens roamed the skies, the heavens, the seas and the land. Whilst heroes and heroines, rulers and conquerors enjoyed great glory in Greece, great rivalries troubled the country too. Based on the myth of Theseus and the Minotaur, King Aegeus of Athens plots war against King Minos of Crete. For years now, he has been forced to send young boys and girls to Crete, where they must try and defeat the Labyrinth and the terrible Minotaur within its walls. None have ever returned. No longer able to afford to send these boys and girls to Crete, Aegeus plots to attack Crete using his army of teenagers - the Trident. The two brothers, unable to return to Earth, must join the Trident and fight against Crete. But what lies ahead for them cannot possibly be expected, and the boys soon find themselves in more danger than they had ever imagined...
