The Man of Three Shouts

What if you were kidnapped and taken to a different planet Earth in the multiverse?The city of Eora (once known as Sydney) where the last human population of Earth struggle to survive, is on the brink of civil war. In a city divided by the harbour, the people of the north shore have the best of the remaining resources and those who live south of the harbour have what is left. For the last 300 years there has been no contact with anyone from outside the city walls. But now there are rumors that strangers have arrived. Where are they from and what do they want? And why are they interested in musicians?
Somebody has to find out and that someone is guitar playing Steve Thales, a south of the harbour musician. Along with his pet guinea pig Barnabus and best friend Brodie, he is transported out of Eora and into the nightmare worlds of the multiverse by the strangers, using an across dimensional travel system known as the Acrodime. He is enslaved by his captors and forced to join a primitive rock band with a beautiful and brilliant but murderous lead singer. Together they travel to different planet Earths across the dimensions of the multiverse to perform, where they face hostile locals, ruthless business entrepreneurs, misanthropic multiverse media moguls and battles with Vikings. Will he ever be able to escape his ruthless captors and find out why the rich and powerful are so interested in his home and save himself, his fellow band members and the people of Eora from total annihilation?
