Excessive mining, human pollution and war have left the earth devastated and all but inhabitable to humans. A Dome built over the city of Sydney and controlled by the tyrant Silmac protects what is possibly the last bastion of civilisation. When Silver is abandoned out in the badlands by her salvage crew, she must fight for survival to make it back to safety. But she soon finds that the Dome no longer offers the protection it once did, as she faces betrayal, makes new alliances and uncovers secrets that will bring her into conflict with Silmac himself.
