'500 years after the Rise...
'The last remaining humans have become numans, dangerously enslaved by a virtual world called the BigDry.
'Wall Manager Macie is an 'incompatible,' unable to assimilate with numan technology due to a disability. As a lowly human, her job is to patch the cracks in the wall that encircles DarwinTwo, protecting the city from the encroaching sea water.
'When numans embark on a dangerous step which will change mankind forever, Macie's job becomes obsolete. There is no room in DarwinTwo for those who don't fit in.
'But perhaps that's exactly what numanity needs.'
