Gavin Meckler has slipped sideways in time again to a far more treacherous future than he has ever faced before.

Ever since Gavin left the world of 2011 and landed 200 years in the future, he has navigated the garden lands of Gardenia, escaped a world run by women in the Squares, and now finds himself in a floating city in the Clouds.

In this possible alternative future, the planet is ravaged by a brutal climate – crippling storms, sweeping winds and an unforgiving sun. Earth's inhabitants have had to adapt, creating a highly sophisticated society where the human race has two options: to live on the earth's scarred surface in enormous culverts, reinforced to withstand the ravages of the weather... or to float above it all.

It is a classless society where everyone must experience life both on the earth and in the clouds... and where they claim to know how and why Gavin has travelled 200 years beyond his own time.

Will Gavin finally understand the truth behind his journey? Can he find his way back to the life he left behind in 2011?

Is there even a world to go back to?...
